How the simulator works
- Every attempt draws a new random set, so a retake is never the same test.
- No explanations or right answers appear until you submit.
- Move freely between questions, change answers and flag any you want to check again.
- There is no time limit; the clock only shows how long you have taken.
- Keyboard: 1–4 or A–D to answer, ← → to move, F to flag.

FAQ
Exam simulator FAQ
How is the simulator different from the mock exams?
Each mock exam is a fixed set of questions, so you can repeat it and compare scores. The simulator draws a new random set of 40 questions from our 272-question bank every time, in the same format, with no site menus, ads or hints on screen.
Are these the real Ontario Class A (AZ) test questions?
No. Every question is original and written from the official study guide, and each answer names the section it comes from. This is a practice simulation, not the official test, and it is not affiliated with the official test provider (Ontario Ministry of Transportation (MTO)).
Is the simulator timed?
No. Our official sources for this test do not give a time limit, so the simulator is untimed. A clock shows how long you have taken, and your time appears with your result.
How is the simulation marked?
You need 32/40 to pass. After you submit, you see your score by section and by topic, then every question with your answer, the right answer and an explanation.
Can I go back and change my answers?
Yes. Until you submit, you can move between questions, change any answer and flag questions to check again. The question map shows which ones are answered, flagged or still empty. The official test may work differently, so check with the official test provider (Ontario Ministry of Transportation (MTO)).
