An AZ-900 plan of 30 hours: stages, skill-group split and an eleven-week dated case
Microsoft publishes no study-hour figure. This plan uses 20 to 40 hours. At 30 hours, 3 hours a week takes 10 weeks, 6 hours takes 5 and 10 hours takes 3, plus about one buffer week for every eight. Split the hours 12, 10 and 8 across the three skill groups.
Cloud concepts feels familiar, so it soaks up hours the larger groups need.
How many hours
Microsoft does not publish a study-hour figure. The CredenTrek book uses 20 to 40 hours as a working assumption: nearer 20 if you already work with IT or Microsoft 365, nearer 40 if the cloud is new to you. Your first attempt at the free practice assessment tells you where you stand.
Tracks at 30 hours
| Track | Hours a week | Weeks at 30 hours |
|---|---|---|
| Light | 2 to 4 | 10 at 3 hours |
| Standard | 5 to 8 | 5 at 6 hours |
| Intensive | 9 to 15 | 3 at 10 hours |
Pick the track from your real week, not your best week. Add about one buffer week for every eight weeks of plan, so a 10-week plan gets one.
Split by skill group
| Skill group and weight | Hours | Study first |
|---|---|---|
| Architecture and services, 35 to 40% | 12 | Core architecture, identity and security |
| Management and governance, 30 to 35% | 10 | Governance tools, monitoring tools |
| Cloud concepts, 25 to 30% | 8 | Shared responsibility, service types |
Candidates often spend most of their time on cloud concepts, because it is the most familiar, although architecture and services carry the largest share.
Stages across 30 hours
| Stage | Share | Hours at 30 | What you do |
|---|---|---|---|
| A, foundation | About 10% | 3 | Rate yourself on every skill area, take the free practice assessment once, set up a safe subscription |
| B, first coverage | About 45% | 13.5 | Work through the Learn path once, with a short portal task per group |
| C, practice | About 30% | 9 | Question sets by group, the service contrasts, review of every wrong answer |
| D, simulation | About 15% | 4.5 | Timed practice in 45-minute blocks, the exam sandbox, light revision |
The four add to 30.
An eleven-week case
Take a candidate with 3 hours a week who wants to sit by 26 February 2027.
- 30 divided by 3 gives 10 weeks.
- One buffer week makes 11.
- Eleven weeks before 26 February 2027 is 11 December 2026.
That is the start date. Mark the end of Stage A, the end of first coverage, and the 45-minute timed blocks in the diary. With 6 hours a week the same plan runs 5 weeks plus a buffer week, and with 10 hours 3 plus a buffer week.
Which route
| Route | What it is | Suits |
|---|---|---|
| Official | Free, self-paced Microsoft Learn paths, plus the free practice assessment and exam sandbox | Self-learners; costs nothing beyond the exam fee |
| Instructor-led | Courses from Microsoft and its training partners | People who learn best in a group |
| Limited time | The free Learn path, the free practice assessment and a safe subscription | Three hours a week or less |
Whatever you choose, confirm that it names AZ-900 and the skills measured as of 20 July 2026.
Readiness
Look for consistent results across two or three attempts at practice questions, no skill group far behind the others, and the ability to explain each contrast aloud without notes.
