PL-300 Practice Exam — Microsoft Power BI Data Analyst
PL-300 checks that you can take data from its source to a shared report in Power BI: shape and clean it in Power Query, build a star schema with the right relationships, write DAX measures with CALCULATE and time intelligence, choose and format visuals that answer the question, and publish, share and secure the result in the Power BI service. Practise across all four official skill areas with full 50-question papers and a score breakdown per skill area.

A sample PL-300 question
One question written for this page, in the same style as the questions in the bank.
Model the data
A matrix shows total sales by product category. You need a measure that shows each category's share of all sales, so that the denominator stays the same whichever category is on the row. Which expression should the measure use?
- ADIVIDE(SUM(Sales[Amount]), CALCULATE(SUM(Sales[Amount]), ALL(Product[Category]))) — Correct answer
- BDIVIDE(SUM(Sales[Amount]), SUM(Sales[Amount]))
- CDIVIDE(SUM(Sales[Amount]), CALCULATE(SUM(Sales[Amount]), VALUES(Product[Category])))
- DDIVIDE(SUM(Sales[Amount]), COUNTROWS(Product))
About the PL-300 exam
How many questions are on the PL-300 exam and how long is it?
Microsoft does not publish a fixed question count, but most of its certification exams contain 40 to 60 questions, and PL-300 gives you 100 minutes to answer them. ReadyForCert papers use 50 questions on the same 100-minute clock.
What score do I need to pass PL-300?
700 on a scale of 1 to 1,000. The score is scaled rather than a raw percentage of questions answered correctly, so it does not map exactly onto “70% of questions right”.
Do I need to know DAX for PL-300?
Yes. Modelling the data is about a quarter of the exam, and most of it is DAX: aggregations, CALCULATE, time intelligence and filter context. You do not need to write long formulas from memory, but you do need to recognise which function a measure needs and why.
Are these the real PL-300 exam questions?
No. These are practice questions written against the current Microsoft study guide. Real exam content is covered by Microsoft's exam agreement, and the bank is refreshed regularly.
