Identify Level of Skills
The first step to cracking the exam is to answer the 14 sample questions on the Tableau official preparation guide (Link) in order to measure your Tableau skills. These skills are divided into:
– Advanced level
if you can answer all questions correctly within 30 minutes,
– Medium level
if you can answer all questions correctly within 1 hour,
– Beginner level
if you can answer fewer than 10 out of 14 questions correctly.
If you are a beginner-level candidate, you are strongly recommended to download the Tableau On-Demand videos (Link) first and go through the sample workbooks on Tableau Desktop before getting in depth into complex customized calculations. However, if you are an advanced level candidate, it makes sense to familiarize yourself with the new features of Tableau Desktop 9 before taking the exam as Desktop 9 provides quite a lot of innovative new features that allow complex calculations.
