The highest-value AI-901 exam-day rules are simple: never leave a question blank, because there is no penalty for a wrong answer; read multi-response “select all that apply” items twice, because missing one option loses the whole mark; and keep your pace to about a minute per question so you can return to the hard ones. The pass mark is 700 out of 1000, and the exam mixes single-answer and multi-response questions. None of these tips replace knowing the material, but on the day they routinely save several marks.
What should you know before you start?
Walk in with the format settled so it does not surprise you:
- Pass mark: 700 out of 1000. A scaled score, not a raw percentage. Source: the official AI-901 exam page.
- Two areas, unevenly weighted. Identify AI concepts and capabilities (40 to 45%) and implement AI solutions with Microsoft Foundry (55 to 60%). More than half the marks are the Foundry half.
- No wrong-answer penalty. Marks are awarded for correct answers; nothing is deducted for incorrect ones, so a guess can only help.
- Mixed question types. Expect single-answer multiple-choice and multi-response “select all that apply” items. The skills were last updated on 15 April 2026.
Microsoft does not publish a fixed question count or time limit for the AI-901, but it is a short Fundamentals exam; plan as if you have roughly a minute per question and you will not run out of time. For the full content map, see what’s on the AI-901 exam.
How should you manage your time?
Treat the clock as a budget, not a stopwatch on every question.
- First pass, answer what you know. Move through the exam answering everything you are confident on. Do not stall on a hard question; mark it for review and keep going.
- Flag, do not freeze. Use the review/flag feature on anything you are unsure of so you can find it again quickly.
- Second pass, the flagged ones. Come back with a clear head; later questions sometimes jog the answer to an earlier one.
- Final pass, fill every blank. Before you submit, make sure no question is unanswered. There is no penalty for a wrong answer, so an educated guess is strictly better than a blank.
Which question types trip people up?
| Pitfall | What goes wrong | The fix |
|---|---|---|
| Multi-response items | Missing one correct option loses the whole mark | Count how many answers are required; re-read before moving on |
| ”Best” or “most appropriate” wording | Two answers look right; one is better | Pick the strongest fit for the exact scenario, not the first plausible one |
| Confusing the Foundry tools | Mixing up the Foundry portal, Foundry SDK and Content Understanding | Match the tool to the job the question describes |
| Over-reading concept questions | Adding nuance the question did not ask for | Answer at Fundamentals depth; do not invent edge cases |
| Rushing the last few minutes | Leaving questions blank under time pressure | Reserve the final pass purely for filling blanks |
The multi-response items and the Foundry-tool mix-ups are where most avoidable marks go. For why the tools matter, see do you need to code for the AI-901.
How do you handle a question you do not know?
Do not gift it away:
- Eliminate first. Cross off the clearly wrong options; even getting from four to two doubles a guess.
- Watch for distractors from the same domain. Wrong answers are often real terms that simply do not fit this scenario, so anchor on what the question actually asks.
- Then commit. With no wrong-answer penalty, an eliminated-down guess is free upside. Answer it and flag it rather than leaving it blank.
What about the logistics?
Sort the practical side so it does not cost you focus:
- Online or test centre. Decide in advance. For an online proctored exam, check your system, webcam and a clear desk beforehand, and arrive early to the check-in.
- ID ready. Have the identification the proctor requires on hand.
- Read the rules for your delivery. Online proctoring has stricter environment rules than a test centre. Confirm pricing, languages and booking on the official AI-901 exam page, since the fee is set by the country or region where the exam is proctored.
The single best exam-day habit
The best preparation for exam day is having already sat the exam under timed conditions a few times, so the format, the pacing and the multi-response wording are all familiar. That is what mock exams are for: not just checking knowledge, but rehearsing the conditions. PassTheVoid gives you a free timed mock that mirrors the 700/1000 pass mark and the official 40-45 / 55-60 weighting, plus a per-domain breakdown so your last revision targets your weakest half. It is free and ad-free, with a one-time Pro unlock for unlimited mocks and the full question bank. Do a final timed run on the AI-901 practice test the day before.
