Simulate the real Microsoft Certified: Machine Learning Operations Engineer Associate (AI-300) (AI-300) exam with full-length timed sessions. Questions drawn proportionally from all 5 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic AI-300 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (100 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free AI-300 mock exam uses the same question distribution as the real Microsoft Certified: Machine Learning Operations Engineer Associate (AI-300) (AI-300) exam. Each session draws questions proportionally from all 5 official blueprint domains published by Microsoft, so the topic mix you see accurately reflects what you'll face on test day.
AI-300 Domain Distribution
Genaiops Infrastructure
Mlops Infrastructure
Generative AI Optimization
Generative AI Quality Assurance And Observability
ML Model Lifecycle And Operations
Every question is checked against the 2026 AI-300 exam objectives and published under the editorial oversight of an engineer with 12+ years' experience. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your AI-300 study plan.
Practice test — for learning
Use the AI-300 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the AI-300 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

Sitting the AI-300 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The AI-300 exam lasts 100 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most AI-300 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Microsoft writes many AI-300 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real AI-300 is a long, focused sitting (100 minutes). In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina.

Passing score
700 (scaled 1–1,000)
Published by the vendor
The AI-300 uses scaled scoring, so the 700 (scaled 1–1,000) passing score is not a percentage of questions correct. Consistently scoring above 80% on mock exams gives you a buffer for unexpected question types on the real exam.
Yes. Courseiva provides free AI-300 mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length AI-300 mock exams before booking your test date. The vendor's passing score is 700 (scaled 1–1,000), a scaled score rather than a percentage, so the buffer accounts for difficulty variation.
Most candidates who pass AI-300 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, AI-assisted and checked against the public Microsoft exam blueprints, with editorial oversight from an experienced network and security engineer. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Microsoft certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
