Edureify vs Udemy: which AB-900 prep actually tells you when you're ready?

The Microsoft 365 Certified: Copilot and Agent Administration Fundamentals (AB-900) is Microsoft's current Microsoft 365 fundamentals exam, in place of the retired MS-900, for IT professionals who know Microsoft 365 core services, identity, and security and have used Copilot and agents; there are no prerequisites. It covers the core features and objects of Microsoft 365 services, data protection and governance for Microsoft 365 and Copilot (including Purview), and basic administrative tasks for Copilot and agents. The exam runs 45 minutes; Microsoft doesn't publish a fixed question count, but candidates typically see 40–60 questions across multiple choice, drag-and-drop, hot area, build list, and active screen items, and a scaled score of 700 out of 1,000 is required to pass.

Edureify runs on one loop: a Diagnostic maps exactly where you stand across AB-900's Microsoft 365 core features, data protection and governance, and Copilot and agent admin areas before you study anything, an adaptive Roadmap turns that into a day-by-day plan weighted toward your actual gaps, a self-paced Practice Loop of questions, mock exams, and spaced review builds mastery topic by topic, and an Intervention layer steps in the moment your progress stalls. Every session feeds back into a live Readiness Score that predicts when you'll be exam-ready and names the specific topics still holding you back — not a completion percentage frozen at the end of a course.

Udemy's appeal for AB-900 prep is choice and price — many independently produced practice-test sets and video courses appeared soon after the exam launched, covering AB-900's Microsoft 365 core features, data protection and governance, and Copilot and agent admin areas, often at low sale prices. Quality varies by instructor, so reviews and update dates matter when choosing one.

The gap is the same one that shows up across any self-paced marketplace: a video course or practice-test set can't tell you specifically which of AB-900's Microsoft 365 core features, data protection and governance, and Copilot and agent admin areas you're actually weak in. You finish knowing you covered the material, not knowing whether you've retained enough to pass.

Edureify's Diagnostic maps your understanding across AB-900's Microsoft 365 core features, data protection and governance, and Copilot and agent admin areas on day one, and the Readiness Score keeps updating as you practice — so instead of a vague sense of completion, you get a specific, evolving answer.
