Microsoft certification: use the free practice assessment before buying a prep course

What Microsoft gives every candidate

Using Azure Fundamentals (exam AZ-900) as the example, the Microsoft Learn page (last updated 20 July 2026) offers a free practice assessment showing the style, wording and difficulty of questions, an exam sandbox to try the exam interface, and an exam study guide listing the topics covered. AZ-900 assesses cloud concepts, Azure architecture and services, and Azure management and governance, and gives you 45 minutes.

Microsoft says the price depends on the country or region where the exam is proctored, so check it at scheduling instead of relying on a figure from another site. The exam is offered in 13 languages, including English, Japanese, Chinese, Korean, Spanish, German and French. Students and educators can schedule through Certiport; others through Pearson VUE.

The retake policy changes your budget

Microsoft's retake policy for role-based, specialty and fundamentals exams says you must wait 24 hours after a first failed attempt, then 14 days between each later attempt, up to five attempts within 12 months of your first. After five failures you wait until 12 months from the first attempt. You pay for each retake where a fee applies, and you cannot retake an exam you have passed unless the certification has expired.

Use the practice assessment as a diagnostic

• Take the assessment once before studying and note which skill areas you miss.
• Map each missed area to a section of the study guide.
• Study those areas with free material, then answer recall questions without notes, as in our retrieval-practice guide.
• Retake the assessment after studying and compare by skill area, not just the total.
• Pay for a prep resource only if one area stays weak after free study.

Worked diagnostic (invented results)

A candidate takes the free AZ-900 practice assessment before studying. Cloud concepts go well; most misses are in management and governance and some architecture components. Instead of buying a full prep course, they study the study-guide sections for the two weak areas, write recall questions and retake the assessment a week later.

If both areas improve and stay improved a few days later, they book the exam. If governance stays weak, the purchase is a targeted resource for that area, not a broad course that repeats cloud concepts they already know.

Two administrative traps

Microsoft strongly recommends registering with a personal Microsoft account. Its page warns that if you register with a work or school account, your exam records will be lost if you leave the organization and cannot be recovered.

Waivers of the retake waiting period are only granted for internet connectivity problems or equipment failure during the exam, and only with a Pearson VUE case number. A bad day is not grounds for a waiver, so do not book the exam right before a deadline that depends on passing. Microsoft also notes you may be eligible for ACE college credit after passing; we have not taken a Microsoft exam, and this guide reflects Microsoft Learn pages fetched 29 October 2026.
