Power BI Certification PL-300: Complete Guide and Free Study Plan

What is the Power BI PL-300 certification?

PL-300 (Microsoft Power BI Data Analyst) is the exam you pass to earn the Microsoft Certified: Power BI Data Analyst Associate certification. It validates that you can prepare data with Power Query, build a data model, write DAX measures, design reports and manage Power BI content securely. It is an intermediate-level, role-based certification and the main official credential for Power BI.

It is aimed at data analysts, BI developers, finance and controlling profiles, and developers who build reports. Microsoft expects candidates to be proficient with Power Query and DAX and to work with business stakeholders to turn requirements into reports.

What are the PL-300 exam details?

The following points come from the official Microsoft Learn certification page and study guide at the time of writing. Exam details change, so always check the official certification page before booking.

Level	Intermediate
Duration	100 minutes
Passing score	700 (on a scale of 1 to 1000)

If the exam is not available in your preferred language, Microsoft's study guide notes you can request 30 extra minutes. Note also that localised versions, including French, are updated a few weeks after the English version, so a French-speaking candidate may see the previous wording of a skill for a short period after an update.

What skills does the PL-300 exam measure?

The skills measured were last updated on 20 April 2026. The four domains and their weights:

Domain	Weight	What it covers
Prepare the data	25–30%	Connecting to sources, choosing Import, DirectQuery or Direct Lake, profiling and cleaning, Power Query transformations, keys, merge and append
Model the data	25–30%	Relationships and cardinality, date table, role-playing dimensions, DAX measures, CALCULATE, time intelligence, semi-additive measures, calculation groups, performance
Visualize and analyze the data	25–30%	Choosing visuals, themes, conditional formatting, bookmarks, drillthrough, tooltips, mobile and accessible design, Copilot features, analytics features
Manage and secure Power BI	15–20%	Workspaces and apps, scheduled refresh, gateways, subscriptions and alerts, endorsement, workspace roles, row-level security, sensitivity labels

Three quarters of the exam is about data and modelling, not just visuals. Candidates who only know how to drag charts onto a page usually struggle with the modelling and DAX questions.

What kind of questions should you expect?

Microsoft exams use several formats: multiple choice, multiple answers, drag-and-drop ordering, "does this solution meet the goal" series, and case studies with a business scenario. Microsoft provides an exam sandbox to try the interface before the real exam.

A typical modelling question gives you a scenario and asks which measure or setting is correct. For example, you should recognise that stock is semi-additive:

Closing Stock =
CALCULATE ( SUM ( Inventory[Quantity] ), LASTDATE ( 'Date'[Date] ) )

Or that dynamic row-level security filters a table by the signed-in user, with a role filter on the Users table such as:

Users[Email] = USERPRINCIPALNAME ()

How do you prepare for PL-300 for free?

Most of the official preparation is free:

• Microsoft Learn learning paths for PL-300: self-paced modules with exercises, linked from the exam page.
• The official study guide: the detailed list of skills measured, to use as a checklist.
• The free practice assessment on Microsoft Learn: questions in the style and difficulty of the exam.
• The exam sandbox: to get used to the interface.
• Exam Readiness Zone videos: Microsoft's preparation sessions per domain.
• Power BI Desktop: free, to practise on your own data.

Paid instructor-led courses exist through Microsoft training partners, including in Morocco, but they are not required.

What is a realistic PL-300 study plan?

For someone who already uses Excel and has basic Power BI notions, around eight weeks at 5–7 hours per week is a reasonable order of magnitude. Adapt it to your level.

Week	Focus	Deliverable
1	Power BI Desktop, Power Query basics	Clean and load two sources
2	Advanced Power Query: merge, append, unpivot, parameters	A reusable cleaning flow
3	Data modelling: star schema, relationships, date table	A complete model
4	DAX basics: measures, CALCULATE, filter context	15 core measures
5	Time intelligence, semi-additive measures, calculation groups	YTD, last year and rolling measures
6	Reports: visuals, bookmarks, drillthrough, tooltips, mobile, accessibility	A three-page report
7	Service: workspaces, apps, refresh, gateway, RLS, sensitivity labels	Published and secured report
8	Practice assessment, weak areas, sandbox	Score consistently above target

Step 1 — Build a real project while studying

Pick one dataset (sales, budget, any open data) and carry it through the whole plan. The Power BI star schema guide and the essential DAX formulas cover weeks 3 to 5.

Step 2 — Use the study guide as a checklist

Tick each bullet of the skills measured only when you have done it in Power BI, not just read about it.

Step 3 — Take the practice assessment twice

Once mid-way to find gaps, once at the end. Review every wrong answer against the documentation.

Step 4 — Book the exam

Register with a personal Microsoft account rather than a work account: Microsoft warns that exam records linked to an organisational account can be lost if you leave the company.

What should you do on exam day?

• Read each case study's requirements before the questions; the details (refresh frequency, security, data volume) usually decide the answer.
• Flag questions you are unsure about and come back to them, keeping an eye on the timer.
• Eliminate answers that contradict good modelling practice: bi-directional relationships everywhere, calculated columns for ratios, time intelligence without a date table.
• If you take the exam online, test your computer, webcam and connection beforehand and prepare a quiet room, as required by the proctoring rules.

How much does the PL-300 exam cost in Morocco?

Microsoft sets the price according to the country where the exam is taken, and it can change. Rather than relying on a figure from a blog, check the price shown when you schedule the exam through the official page. Microsoft also runs offers from time to time (such as Exam Replay, which includes a retake) and student pricing exists in some countries; check what applies to your situation on the official page.

Is the PL-300 certification worth it?

It depends on your profile.

• Career changers and juniors: it gives a structured programme and a verifiable credential, useful when your experience is still limited. It works best together with a portfolio of real reports.
• Experienced analysts: it mainly formalises skills and fills gaps (security, service administration, newer features).
• Recruiters in Morocco: Power BI appears often in data analyst and BI offers in Casablanca and Rabat, in banking, insurance, telecoms, retail and consulting. A certification can help a CV pass the first screening, but interviews still test real modelling and DAX skills.

A certification does not replace demonstrable work. Two or three well-documented dashboards often say more than a badge alone.

How do you renew the PL-300 certification?

The certification is valid for 12 months. You renew it for free by passing an online renewal assessment on Microsoft Learn, without retaking the full exam. Microsoft notifies you when the renewal window opens.

Conclusion

PL-300 is the reference certification for Power BI: 100 minutes, a passing score of 700, four domains dominated by data preparation and modelling, and free official preparation on Microsoft Learn. Follow the study guide as a checklist, build a real project in parallel, and use the practice assessment to measure your progress.
