PL-300 Study App: Power BI Concepts, DAX and Data Modelling Recall
PL-300 is Microsoft's exam for the Power BI Data Analyst Associate certification. It tests whether you can prepare data, model it, visualise and analyse it, and manage Power BI content. Much of that is hands-on skill you build in Power BI Desktop and the Power BI service. The rest is knowing the concepts, DAX functions, settings and trade-offs well enough to pick the right answer quickly. Type to Study helps with that second part.

What PL-300 covers
Microsoft publishes a study guide for PL-300 that lists the skills measured, grouped into areas such as preparing the data (Power Query, data sources, cleaning and shaping), modelling the data (relationships, star schemas, DAX measures), visualising and analysing (reports, visuals, insights) and deploying and maintaining assets (workspaces, security, sharing).
Microsoft updates the skills measured and the weighting of each area from time to time, sometimes to add newer Power BI and Fabric features. Read the current study guide on Microsoft Learn before you plan, and check the exam page for format, price and scoring in your country.
Why it is hard and how to prepare
PL-300 questions are often scenarios: a business need, a data model, and a choice between similar options such as which DAX function, which relationship direction or which storage mode. You need real experience to recognise the right answer, and you need precise knowledge of names and behaviours to avoid the near-miss options.
Build both. Work through Microsoft Learn's free learning paths and do the exercises in Power BI Desktop on a sample dataset. Alongside that, test yourself on the concepts: the difference between calculated columns and measures, filter context and row context, CALCULATE, star schema rules, row-level security. Retrieval practice (Roediger and Karpicke, 2006) and spacing (Cepeda et al., 2006) make that knowledge stick.
A plan using Type to Study
Write notes per skill area as you study: DAX functions with one-line explanations, modelling rules, Power Query steps, and security and sharing options. Upload them, or type a topic such as "DAX filter context explained" to get a researched lesson with sources listed.
Read each lesson and type the key definitions once, then run the recall pass with the key terms hidden. Flashcards bring back the DAX functions and settings you miss. Before the exam, take a timed final exam across your units, then go back to Power BI Desktop for the topics it flags.
- Type to Study helps with concepts, DAX function knowledge and recall, not with hands-on Power BI practice
- It has no official Microsoft exam questions; use Microsoft Learn's practice assessment for exam-style questions
- Upload only your own notes and material you are allowed to copy
Questions
Does Type to Study include PL-300 practice questions from Microsoft?
No. It builds quizzes from your own notes and topics. Microsoft Learn offers a free practice assessment for exam-style questions.
Can I learn DAX with Type to Study?
You can learn what each DAX function does, its syntax and when to use it, and test yourself on it. Write and test real measures in Power BI Desktop.
Is PL-300 still the current Power BI exam?
At the time of writing, yes. Microsoft changes exams and retires old ones, so check the PL-300 page on Microsoft Learn before you book.
