How to Create a Rounded Bar Chart?

Rounded Bar Charts are an aesthetic version of standard bar charts. Portraying the ranks of values or comparing measures can be effectively done with these charts. Bars are a robust tool to analyze categorical data and perform comparative study. One area of concern with Rounded Bars, is that the ending curves tend to extend slightly below or over the boundary values. This can give rise to precision issues for some cases. The steps to create a Rounded Bar Chart are below.

How to Create a Lollipop Chart?

Lollipop Charts are a modified version of bar charts. They offer a visual alternative to side-by-side bar chart, or a Gantt chart. A Lollipop Chart is a bar plot in which the bar is transformed into a line and a dot, with adjusted sizes to create a Lollipop effect. It shows the relationship between a numeric and a categoric variable.    ✍   The benefit of a Lollipop Chart is it's aesthetic appeal. The colors and sizes of the bar and dot can be customized to give a light and less cluttered feel as compared to a standard bar chart. In data visualization, we have a dreaded thing known as the MoirĂ© effect, which is nothing but a visual perception when viewing superimposed lines and dots resulting in poor readability. A Lollipop chart helps avoid a MoirĂ© effect. The steps to create a Lollipop Chart are as below.

How to Create a Barbell Chart?

Barbell Charts are also known as DNA chart, Gap chart, Dumbbell chart, and Connected Dot Plots. It illustrates the change between two or more data points. The effectiveness of a Barbell Chart is its ability to clearly illustrate the change or distance between groups of data points. It compares categorical data, and uses bars to measure the gap, and circles to highlight values. The steps to create a Barbell Chart are as below.

How to Create a Bar in Bar Chart?

Bar in Bar Charts stack one bar over another bar. In a Bar in Bar chart, each bar is assigned a unique color and unique width to identify them easily when they overlap. These charts are useful for showing progress towards a goal, or for comparing measures for different periods, when both the bars have the same starting point. The below tutorial illustrates the steps to create a Bar in Bar chart.

How to Create a Stacked Bar Chart?

Stacked Bar Charts allow comparison of components across categories, and how a larger category is divided into smaller sub-categories. Stacked Bar Charts help discern the relationship of each part with the whole, also known as part-to-whole relationship. It also helps identify which series contributes the most for making a total bigger or smaller relative to another, example while comparing Sales of USA Regions for a Store. One limitation of Stacked Bar Chart is for bars far away from the axis, it becomes visually complex to compare their sizes due to inconsistent baselines.    ✍   A Stacked Bar Chart can be a Simple Stacked Bar Chart, or a 100% Stacked Bar Chart. A Simple Stacked Bar Chart displays the full value of the bar with the corresponding Segment Values. A 100% Stacked Bar Chart shows the percentage of every Segment in relation to the whole value. The below video explains how to create a Stacked Bar Chart in Tableau of both types.

   ✍   Another approach to create a Stacked Bar Chart when we want to display multiple measures contributing to individual members of a dimension is explained below. Here also we can have a Simple or 100% Stacked Bar Chart. The steps to create a Stacked Bar Chart in this approach are detailed below.

How to Create a Radial Bar Chart?

Radial Bar Charts allow us to explore the advanced capabilities of Tableau Calculations and create curves and arcs. Radial Bar Charts can result in some stunning attractive designs. In this type of chart, the bars are displayed on a Polar coordinate system instead of a Cartesian system. In a Radial Bar Chart, the bars on the outside are longer than the bars inside for the same value, so we cannot use length of the bars to compare the values. Radial Bar Charts are used in a variety of business and journalism scenarios to illustrate ideas and derive insights. The steps to create a Radial Bar Chart in Tableau are below.

How to Create a Radial Column Chart?

Radial Column Charts are a modified visualization of our usual vertical column charts. In this type of chart, the bars are projected outwards from the center. In a Radial Column Chart, the heights of the different bars provide details for a comparative study, and helps determine outliers by noticeable height differences. An optimum number of bars is recommended in this type of chart, to avoid congestion with many bars packed closely. Radial Bar Charts can help create spectacular and eye-catching visuals. The steps to create a Radial Column Chart in Tableau are as below.

How to Create a Doughnut Chart?

Doughnut Charts are a modified version of Pie Chart where there is a hole in the center. A Doughnut Chart helps measure part-to-whole relationships. Visually, we are better able to analyze an arc length than the size of a pie slice, which is exactly what a Doughnut Chart provides, thus enhancing readability. The additional benefit with the hole in a Doughnut Chart is now we have more empty space to add labels and details to our visualization. Sometimes a Doughnut Chart encompasses two rings instead of one, for scenarios when we are depicting two sets of data, each ring with its own number of arc slices. The steps to create a Doughnut Chart in Tableau are below.

How to Create a Pareto Chart?

Pareto Charts are based on the Pareto Principle which helps identify the vital (20%) inputs producing the maximum (80%) results. The inputs are displayed in bars in the order of importance and value. Vilfredo Pareto (1848 - 1923), noticed that 20% of the pea pods in his garden were responsible for 80% of the peas. Pareto expanded this principle further to macroeconomics by showing that 80% of the wealth in Italy was owned by 20% of the population. The 80-20 rule, also known as the Pareto principle, was introduced in 1906.
   ✍   In the example above we saw how the % of Total Sales and the % of Product Count are adhering to the 80-20 rule. Now let's complete our Pareto Chart by adding the bars. Each bar will depict the Sales of each Product Sub-Category in descending order. This will allow identifying the members driving the highest Sales.

How to Create a Gauge Chart?

Gauge Charts are a form of half Pie Chart with a needle indicating the data value. It helps depict the change of a linear progressive value, or the changes of different entities over a common parameter. Gauge Charts are widely used in dashboards and reporting to illustrate Key Performance Indicators across all industry domains. The below video walks us through the steps to create a Gauge Chart in Tableau.

How to Create a Thermometer Chart?

Thermometer Charts help represent the existing value of a measure as compared to a target value. The progress and completion can be interpreted easily by looking at the chart due to the prominent color contrasts in effect. A Thermometer Chart provides an impactful presence in any dashboard and is very intuitive to look at. The chart is frequently expressed as a percentage of the whole, with a darker or lighter color representing the progress on a contrasting color space which gives the appearance of a rising thermometer mercury. The steps to build a Thermometer Chart are as below.

How to Create a Span Chart?

Span Charts help determine the difference between the values of two data points. The difference in values can either be between the maximum and minimum values of a particular category, or between two values from two distinct categories. The extreme endpoints of a Span Chart are often formatted for aesthetic and appealing designs. A Span Chart is also known as Floating Bar Chart, Difference Chart, High-Low Chart, and Range Bar Chart. This type of chart enables us to add more information and details in the space created by eliminating the bases of the data points. The steps to create a Span Chart are as below.

How to Create a Waterfall Chart?

Waterfall Charts are a frequent form of data visualization which depicts the cumulative effect of sequentially introduced positive or negative values. The intermediate values can be category based or time-based, and helps interpret the flow how one balance moved to another balance. The Waterfall Chart is also referred to as a Flying Bricks chart, or Mario chart. Often in finance, it will be referred to as a Bridge Chart. The steps to create a Waterfall Chart in Tableau are as below.

Mandatory Tutorials

   ✍   Learning Tableau requires some strong foundations initially on which we can build on later. There is an interesting analogy by Elon Musk, the mastermind behind SpaceX and Tesla Motors, to view knowledge as a semantic tree. Make sure you have a robust foundation of the fundamental principles and concepts, i.e. the trunk and the big branches. Only after that, we can move on to the details, i.e. the leaves and the small branches. This approach works remarkably in accelerated learning at later stages. Investing 5-6 hours is an affordable price to pay for each of the below videos to garner crystal clear concepts.
   ✍   For Learning Tableau from the basics and skilling up to the next level in a few hours, the below video tutorial is a pretty nice fit. It walks through the essential components, features, functionalities, and use cases for the tool, along with interactive demos. It is recommended that you practice the concepts hands-on along the way as the tutorial progresses. This will give a nice feel of how the tool responds to various analytical features while using the datasets. Some concepts like Table Calculations can be best assimilated while viewing the results of the dataset on which we are applying the logics during hands-on.
   ✍   For an exhaustive learning experience, devote a few hours to the below tutorial. This video is elaborate, and deep dives into the finer concepts of Tableau. It is recommended that you practice with as much variety of datasets as possible, since the Super Store dataset is seldom used in any exams. Many of the times the datasets span across samples from industries and businesses that we see in our daily lives. Having frequent exposure to such datasets will help you understand the variety of use cases where we can use Tableau to derive insights.
   ✍    The below Tableau Tutorial provides you with a comprehensive exposure to the tool and related concepts. Plan to complete it in multiple seatings, to make the most out of this content-rich long video. It is recommended that you become thorough with the initial concepts first even though some may seem optional, before you plan to skip to the advanced visualizations. Many of the calculations and functions used in the tool later for appealing charts and catchy visualizations will be using the concepts that you will learn below.

We are often posed with the question on How to pass the Tableau Desktop Specialist Certification Exam since there is such a variety of opinions around it with always changing question patterns. We are glad to let you know that the Tableau Desktop Specialist Certification Exam can be passed effectively with only 12-16 weeks of strategic reading and practical problem solving. If hundreds of our candidates are able to achieve this Certification, there is no reason why you should wait.

We will share our Top Tips to pass the Tableau Desktop Specialist Certification Exam.

Tip #1: Know your Exam

We cannot stress enough how crucial it is for you to go through the Tableau Desktop Specialist Exam Guide and solve it's sample problems. You can download it from the References section of the Menu above. The Exam Guide will give you a crisp glimpse of the entire exam in just a few questions. It is extremely well thought through and you will realize you might be struggling in some of the questions. Keep a note of the questions and then go back to the topics which it pertains to, you may need to improve and read more on those topics.

Tip #2: Essential Videos

The Tableau Tutorial Videos are mandatory if you have not taken any online courses. Also make sure to go through the topics in the Tableau Help Guide. Besides that, check out our collection of videos listed in the section above on How to prepare for the Exam? Here we will recommend some more videos for Advanced Learning.

On Table Calculations, we recommmend you to go through the below videos to get an exceptional understanding from Tableau Ambassador Anthony Smoak.
Another exceptional Table Calculation presentation below by reknowned Tableau Zen Master Andy Kriebel, who is the Head Coach of The Information Lab Data School in London.
On Level of Detail (LOD) Expressions, here is a thorough walkthrough on FIXED, INCLUDE, EXCLUDE and more by Bora Beran, Staff Product Manager at Tableau. You are not expected to write calculations during the exam. But it can help you with conceptual questions, or help you get to answers quicker if you want to solve a question by using your own calculations.
Parameters form an integral part of Tableau learning, the video below by Andie Kriebel will cover all the essential details in a brilliant way. You will not be asked to create or navigate using parameters during the exam but this knowledge can boost your overall score with crystal clear understanding.

Tip #3: Key Focus Areas

The Tableau Desktop Specialist Certification Exam has Conceptual and Theoritical questions you are required to answer correctly to achieve a good score. The Exam Guide from the References section of the Menu will give you a comprehensive list of all topics. Among them, we advise to take special attention to the below key areas and practice quizzes from our Exams here: Extract vs Live connections, Purpose of .TDS files, Join, Blend, Union, Types of Chart, Analyzing Maps using geographic data, Combined axis chart, Dual axis chart, Stacked bar, Group, Set, Uses of a Context filter, Reference lines, Trend lines, Table calculations, Histograms, Parameters, Shapes, Size of Marks, Add interactive or explanatory elements to Dashboards, Dashboard layout for mobile devices, Story, Sharing a twbx, Dimensions and Measures, Discrete and Continuous fields, Aggregation of Measures.

Tip #4: Practice

Practice is at the heart of Tableau. Solving practical problems multiple times daily will make sure you are well acquainted with the tool and can derive any insight whenever asked for. This will come handy during your examination as you can save your energy for the complex problems later, instead of getting exhausted with the easier ones. And with a huge collection of Tableau Desktop Specialist sample questions exactly like what you can expect in the main exam, you have all the tools you need here at LearnTableau.Technology.

Tip #5: Google

Google can be a blessing if you know how to use it effectively. Even though you are not permitted to use resources from your local machine or refer books, you can search online for answer to any question. However, do not spend much time if you cannot find an answer for more than 5-10 mins. The rules that apply to searching online are that you cannot login to some website to get your answer, or visit a chatbox to ask your answers.

From your online search results, we recommend visiting the links of the Tableau Help Articles first. Often the answers are created in such a way that the verbiage will exactly match with the Tableau Help Guide. If you cannot find your answers in the Tableau Help Guide, move on to the other search results. Wherever possible, try to answer the questions using Tableau Menus and Navigations instead of searching online. Questions like how many types of Trend Models are available for a Trend Line can be best answered using the tool itself.

Tip #6: Get to the answer

Tableau does not restrict how you arive at your answer as long as you get it right. Thus whether you write a FIXED calculation to derive Customer Sales for 2019 or whether you use a Year filter and get to the required Sales figure does not matter. The Tableau Desktop Specialist Certification Exam does not require you to write calculations, but that does not mean you cannot if you want to, often it helps get to answers quicker if you are comfortable with LOD and Table Calculations.

The Tableau Desktop Specialist Exam questions span across all categories from conceptual, to insight-driven, to connecting various types of data, and to intensely analyze and explore data from various practical datasets. Exposure to a variety of datasets and being able to analyze them effectively is a key skill in Tableau. You only get one attempt per device for our free test. Based on the scores of thousands of test takers, we would advise you to be active in Tableau for at least 12-16 weeks with various hands-on and theoretical problems before attempting this test to make the most out of this opportunity.

Optimizing your Score

Tableau assesses your skills on different categories - Concepts, Connecting and Preparing Data, Analyzing Data, and Sharing Insights. You can download the Specialist Guide from the 'References' in the Menu above. Being strong in only one area and appearing for the exam can prove fatal. Unless you are well adept in every area, you are taking a gamble on your luck. Improving your score in Tableau is possible only through rigorous practice and well-planned topic areas to study. If you would like further guidance, take our practice tests, or use the Contact option from the menu and reach out to us. Mention which email id you used to give our practice exam along with the date and time. We will review your results and send you a personalized feedback.

Continuous Assessment

Tableau does not provide you detailed assessment score breakdown results after you complete the Certification Exam, so you will never know which questions you need to improve upon or which questions you answered correctly. That's why taking our Practice Tests is critical where we provide you real-time results as you progress. Tableau clearly states that their exams are designed to measure skills, not enable skills. Hence their report only shows high level topic areas with percentage scores without further granularity.

Understanding Dumps

Well, it is no wonder that we are all enticed by a notion of a Tableau Desktop Specialist Certification Dumps, that can enable us to pass the coveted Desktop Specialist Certificate with lifelong validity within a couple of days. But it can prove fatal during your exam if we take a route of Dumps. We encourage Learning Tableau. The concept of Dumps is not appreciable at all. It never helps learning, and is counter-productive. So if you are looking for a quick way to pass the test, Tableau does not work that way.

Accessing our Dumps

However, if you can pass all our quizzes comfortably, chances are high you will pass the main exam. The Tableau Desktop Specialist Dump PDF can take a break for awhile. Tableau strongly emphasizes you must practice with the tool before appearing for the exam, that's why we request you to practice all our tests prior to the main exam. You can read more at our Tableau Certification Dumps.


Let's discuss a topic which can help us during the Tableau Desktop Specialist Certification Exam. If we have worked in a data base that has significant gaps in its data collection, we know it can keep us from viewing a complete picture of our entire data set when we import it into Tableau for analysis. We will have to scaffold as Tableau will just represent rows of data where there is an empty row representing a missing field or key. We can easily create a data scaffold from Tableau. Let's find out how to do this using Tableau.

Or perhaps, a situation where we have to fill in the missing dates and values to present it based on the requirements. Data Scaffolding technique is a great way to create visualizations that are not possible with the original data source. This technique saves time and effort for the data architecture. Knowledge of these techniques can come useful in the Desktop Specialist examination.

What is Data scaffolding

Data scaffolding is an artificial technique to create a data structure for the purpose of better or fill-in-the-gap visualization. In short, it reshapes the data structure to fit the design of the visualization.

The majority of companies these days are using data management systems as part of their business practices. Tableau has been making its way into the medical industry as well. Data scaffolding helps data administrators create, view, and manipulate data without having to learn complex SQL and Java. Problems requiring scaffolding are common in the Tableau Desktop Specialist Certification Exam. A visualization specialist can create charts and graphs in Tableau that show exactly what the data would look like if stored in a relational database.

The scaffolding and joining techniques shared here are helpful at any time when we need to combine data sources for different analysis levels. This is especially useful for applications where the scaffold data set may still require blending, but the modeling methods can be changed depending on how we want to handle the joining, such as using a contribution in conjunction with Data Ink Ratio Animation and how to apply it in Tableau. Scaffolding can also be useful to fill gaps in the data source, especially when trying to represent values from multiple data sources.

Data Pre-Processing

Data Scaffolding is Data Pre-processing too. Data pre-processing describes the processing that is carried out on raw data before preparation for the processing processes. In general, data pre-processing is the process of transforming the raw data into a format similar to the format that is being studied and processed, but in a different way. The feature encoding performs a transformation of the data so that it can be accepted as input into an analysis, visualization or  machine learning algorithm without losing the original meaning encrypted by the features.

Data Pre-Processing can be performed by using various method but the most common ways are by using in-built Tableau functionalities, Excel, or Python Script. Data Pre-Processing requires not only patience but attention to details in finding errors in the dataset as it would affects the quality of the result. Garbage in and Garbage out. So need to be careful for such types of problems to accurately perform pre-processing during the Tableau Desktop Specialist Certification Exam. 

Case Study

Be it that you are a student or someone in the Data field, real world data are no rainbows and magic. Real world data could be really messy or noisy as it may contains a lot of missing data, errors, inaccurate values and so on.  Data cleaning or Data Pre-processing is the part where patience takes place as we would need to design and clean the data so it would suit the visualization as required.


Sarah is given 2 columns of data to perform a high-level analysis for a client but the client would love to have daily data analysis. The data presented by the Client is taken from xxx API and the API would only provide monthly user data.

How to create daily date from monthly data?

Data Scaffolding could address the issue by creating an artificial sheet to support the missing date values. The end goal of this issue would be creating a daily date skeleton column out of the Monthly Date Column and populate the daily users' values by calculating Average Users Per Month.

Desired Result: 

How to create daily date from monthly data? (Step By Step Guide)

Step 1: Create a new sheet with a list of Date (e.g. 1-Jan-2020 to 31-12-2020) with Excel, save as “Date.csv”.

Step 2: Import the original data source.

Step 3:
Import the “Date.csv” files -> Click On “Full Outer” 

Step 4: The Join should result in the table below. In this use case, we would replace the Average Number to the blank rows. (e.g. 1st Jan 2020 has an Average of 2,323 Users)

Final Step: Replacing the blank rows with the previous numbers.  Right-click on the measures -> Add Table Calculation ->  Select “Running Total” and “Specific Dimension

Steps Breakdown (Data Scaffolding)

Step 1 : Create a Date (1-Jan-2020 to 31-Dec-2020) list in Excel Sheets, Save As “ Date.csv”
Step 2 : Import Original Data Source (yourData.csv or any source) into Tableau
Step 3 : Import “Date.csv” into Tableau
Step 4: Perform Outer Join between (yourDate.csv and Date.csv)

To Fill In The Blank Values 

Step 1 : Right Click on Measure Pills ( Sum(Users))
Step 2 : Select “ Add Calculation Table”
Step 3 : Select “Running Total” as Calculation Type
Step 4 : Compute Using “Specific Dimension”

The steps above would resolve the issue of creating daily date out of monthly data without needing help from a database or SQL expert within Tableau! 


The great thing about the Tableau software is that it can deliver quality analysis results even without any programming knowledge. One of the reasons it has become so popular is that its drag-and-drop interface is relatively easy to use, and users without programming knowledge can easily manipulate the data to create a variety of interactive visualizations. This knowledge is thoroughly evaluated during the Tableau Desktop Specialist Certification Exam.

However, to be an exceptional Tableau Developer, it is important to understand that Tableau is something beyond drag and drop, it is very flexible and customizable based on requirements. There are a lot of workarounds in achieving the end goal of a dashboard. At times, we would not need to modify the database. 

On the other hand, it is important to understand the data structure. Data Structure would assist us in designing a better functional dashboard rather than merely showing the generic reports. It is really useful during communications with the backend guy when we need their professional help in building the data source. Furthermore, we could do a simple query from the Database without the help of the backend guys too to speed up our dashboard.

System Setup:

The Tableau Desktop Specialist Exam requires an environment with optimal connectivity speed between 4 Mbps download and 2 Mbps upload, Google Chrome browser, webcam, microphone and an isolated seating arrangement. On the Loyalty Exam Services dashboard, a countdown timer will reflect how much time is left before you can begin the Exam.

Countdown Timer:

When the countdown timer comes down to 60 seconds prior to your scheduled Exam time, a Take your Exam button will appear in it's place. Proceed and make sure your webcam and microphone are enabled. LES says you cannot connect early, but there is a 15 minute grace period if you arrive late.

Connect to Proctoring:

Once you proceed, you will get the tab Start Exam" to begin your Scheduled Exam.
Next when you click "Connect to Proctoring, there is a delay where you are expected to wait until you see a Proceed button. The wait time can vary between 10-30 minutes.

ID Verification:

When you click on Proceed, a GoToMeeting session will be launched which will be used for the entire duration of the Exam. Get ready now with your Government issued ID for verification with the Proctor. The Proctor will contact you via phone or email if there are any issues. When requested by the Proctor, you will start your ID verification by holding your Government issued Photo ID infront of the webcam, wait for a few seconds to focus until the Proctor can clearly see the details and confirms you.

Environment Review:

The Proctor will then require you to rotate your webcam 360° to make sure you are alone in the room, your desk is clear, and there are no unauthorized display screens or monitors around you. This essentially requires standing up with your laptop and turning it 360° so that the Proctor can see. If your connection fluctuates, or there are miscellaneous items in your room or desk, this step can take awhile.

Agree to continue:

Once the Proctor has completed your ID verification and environment review, a list of Rules and Agreements of the Exam will be read out to you, same as the ones mentioned above. You are required to audibly confirm Okay for each Rule mentioned by the Proctor. The Proctor will then help you get connected to the internet server where you will receive the optimal upload and download speed. This entire process can take 10-40 minutes. At any time if you face issues, you can reach out to 855-EXAMITY or email

Virtual Machine Access

Now that you are all set, the Proctor will help you connect to a Virtual Machine which has Tableau installed, along with all the data files required for your Exam. At the beginning of the Exam will be information about how to answer the questions, how to flag the questions you want to come back at later, etc. You get an additional 5 minutes to go through these instructions.

Feel at Home

As you start answering the questions, you will realize the questions are similar to the ones you practiced above at the Free Complete Tableau Desktop Specialist Practice Exam, the Premium Desktop Specialist Practice Exam, the Premium Tableau Connecting Data Exam, the Premium Tableau Analyzing Data Exam, the Premium Tableau Sharing Insights Exam, and the Premium Tableau Concepts Exam. Our extremely affordable brilliant exams will now help you breeze through the main Exam questions.

Slow and Steady

There is no need to rush as there is ample time, if you have been able to pass our Practice Exams above, you will comfortably score more than 90% and also finish answering all the questions in 40-45 minutes in this Main Exam. The questions are multiple-choice and some have more than one correct answers, so besides radio buttons you also have checkboxes. You can access Google or Tableau Help Guide from the browsers inside the Virtual Machine. You cannot use any application from your local machine during the exam. The Virtual Machine does not have Microsoft Excel to make sure you only use Tableau to derive your answers.

Mouse, Keyboard & Display

Since you will working in a remote Virtual Machine, your mouse clicks and response times will often be delayed by a few milliseconds, not enough to hamper the exam though. Also Alt+Tab will not work to switch between windows in your exam environment since it is in a virtual machine, you can switch windows manually which is what most candidates do. Or else if you have the luxury of a large screen monitor, you might put the questions window and Tableau application side by side as you answer the questions. Make sure to read more on External Monitors in the Rules of the Exam section above.

Mark Questions for Later

As a best practice, we recommend flagging and marking questions that might require online searches, or if you are not sure of, and then skip to the next one. Once you reach the end of the test after finishing all the questions you were confident in, revisit the marked questions one by one. This enables efficient use of your time, nervous stability, and moral energy.

Searching for Answers

During online search, prioritize the search results from the Tableau Help Articles first, usually the Help Articles of Tableau are precise and you should be able to find the answer in 10-15 seconds. The Exam questions sometimes even contain exact text from the Tableau Help Articles, though this trend is becoming less prevalent now. Move on to the other search results if you have finished searching from the Tableau Help Guides. We recommend to answer the questions using Tableau instead of searching online as it is often faster that way. Questions where you have to answer on Menu options, Marks card properties, Analytics pane features, Dashboard actions and similar can be easily verified using Tableau and you can answer faster with greater confidence.

Use Clean Sheets

As you address each question, you will realize the need to make different joins, edit the data source, blend, filter, and various other customizations to answer a question. For the next question, even if it uses the same data source, and part of the question seems similar to the earlier questions, do not spend time reusing and modifying the old sheet. Start off with a clean workbook or worksheet for every question. This is a key tactic followed by successful candidates.

Rename the Sheets

To optimize your review at the end of the exam, it is preferable to rename the worksheets with your question number to allow you to quickly refer the correct sheet. For multiple choice questions, make sure to select all possible answers that are applicable to that question by selecting the checkboxes. Often a choice may seem out of place, if required spend a couple of minutes to verify if that choice should be selected or not.

The role can be categorized into Identity Verification, System and Configuration Setup, Accessibility Enablement, Rules and Regulations Enforcement, Supervising the Exam, Addressing Adhoc Accessibility or System Issues during the Exam, Ensuring Closure of the Examination.
