Turn your Power BI experience into PL-300 exam readiness.
Structured for analysts who already use Power BI and need a focused path through the Microsoft Power BI Data Analyst PL-300 exam: concepts, DAX, Power Query M, exam traps, 160 interactive questions, and a timed mock exam.
Study by the skills Microsoft currently measures
The curriculum is aligned to the Microsoft PL-300 study guide skills measured as of April 20, 2026. The official weighting places Prepare the Data, Model the Data, and Visualize and Analyze Data at 25–30% each, and Manage and Secure Power BI at 15–20%.
Module 1 — Prepare the Data
Learn how Power BI connects to data, profiles its quality, transforms it in Power Query, and controls loading and refresh so the resulting model is accurate and efficient.
6 focused concepts → 25–30%Module 2 — Data Modeling
Learn how fact and dimension tables, grain, relationships, date roles and calculated objects work together to create a semantic model with predictable filtering and strong performance.
5 focused concepts → Core modeling skillModule 3 — DAX & Filter Context
Learn how DAX evaluates measures by understanding filter context, row context and context transition, then apply those ideas to iterators, filter modifiers, time intelligence and reusable calculations.
6 focused concepts → 25–30%Module 4 — Visualize & Analyze Data
Learn how to choose and configure visuals for the analytical question, control filtering and navigation, design accessible reports, and use analytical, AI and specialized reporting features appropriately.
7 focused concepts → 15–20%Module 5 — Power BI Service & Security
Learn how workspaces, Apps, permissions, RLS, dashboards, gateways, refresh and governance features work together to distribute and secure Power BI content in the Service.
6 focused concepts → Cross-domain reviewModule 6 — High-Value Exam Extras
Learn the less frequently used but exam-relevant features that experienced analysts can overlook, including paginated reports, dashboard tiles, AI visuals, DirectLake, calculation groups, DAX query view and visual calculations.
7 focused concepts →Focus on the gaps that practical experience can leave

Before you start
Will my progress sync?
No. Progress is stored in localStorage on the browser/device you use. Changing browser, clearing site data or switching devices can make progress unavailable.
Is the mock score official?
No. The site shows a raw study percentage. Microsoft's certification exam uses scaled scoring; use the mock to diagnose strengths and weaknesses.
Is this an exam dump?
No. Questions are original study questions designed around tested skills and common decision patterns, not copied live exam content.
