Great fit if you want the official material the exam is written against
Poor fit if you learn better from video; choose Savill or Pluralsight
A single video of about 1 hour 24 minutes that reviews the AB-900 skills list point by point. It works as a quick check of what you know rather than a first course.
Great fit if you want a fast free review before the exam
Poor fit if you are completely new to Microsoft 365; start with Microsoft's path
A video path of three courses and about 9 hours, mapped to the AB-900 skill areas: Microsoft 365 core features, data protection and governance, and basic administration of Copilot and agents. A practice exam is included.
Great fit if you already have a Pluralsight subscription
Poor fit if you would pay for Pluralsight only for this exam; use Microsoft's free path
Microsoft Press cert-prep videos of 3 hours 25 minutes, taught by Andrew Warren, with about 20 lessons across the exam's main areas. The course was released in March 2026 and is rated 4.6 from 90 ratings.
Great fit if you have LinkedIn Learning through work, a library or LinkedIn Premium
Poor fit if you do not want another subscription; use Microsoft's free path
For most people, Microsoft's free learning path, because it is written against the exam. Pluralsight and LinkedIn Learning suit people who prefer video and already have a subscription.
Yes. Microsoft's learning path, its free practice assessment and John Savill's cram video cover the exam. Add a paid practice set if you want more timed runs.
The video courses here run from about 1 to 9 hours. Plan for about 20 hours of preparation in total, from 10 to 30 depending on your Microsoft 365 experience.
No. It is a fundamentals exam. Admin experience shortens your study time, and complete beginners should start with Microsoft's path rather than the cram video.
