What the AMC CAT MCQ actually looks like
The AMC MCQ is 150 questions in one 3.5-hour session. Each question has five options and one best answer. It is computer adaptive: answer correctly and the next question is harder; answer incorrectly and the next one is easier. There is no negative marking. Results are reported on a 0 to 500 scale, and a pass is described as 250. From 2026 the AMC raised the pass standard slightly. The format and the reporting scale did not change.
The rule that changes everything: no going back
You must answer each question before the next one appears. Once you answer, you cannot go back and change it, and you cannot skip a question and return to it later. The AMC also expects you to finish all 150. If you don't, your result can be recorded as "Fail – insufficient data". So "flag it and come back" is not a strategy here. Every question gets one decision, made once.
84 seconds, 150 times
3.5 hours is 210 minutes. Spread across 150 questions, that is about 84 seconds each. That is an average, not a rule. Some questions take 40 seconds. Some take two minutes. The danger is drift. Two minutes on question 20 feels harmless, but you pay for it at question 130. Candidates often say the last hour is the hardest stretch, when they are tired and behind. So practise full 150-question blocks in 3.5 hours, not only 25-question sets. Then check your pace in quarters: questions 1–38, 39–75, 76–113 and 114–150. If your time per question or your accuracy drops in the last quarter, that is a training target, not a knowledge gap.
First, understand what you are training for
Every question asks for the single best answer, and the AMC warns that other options may be partly correct. Knowledge is the foundation. But the exam also rewards spotting the key clue fast, ruling out the nearly-right options, and committing.
Stop measuring preparation only in questions completed
A candidate can complete thousands of questions and keep the same weak spots. Better questions to ask: Which subjects are weak? Which errors repeat? Does my pace slip after question 100? Do I lose minutes stuck between two plausible options? When I switch options before clicking Next, does it help me or hurt me? Those answers tell you what to train next.
First instinct or second guess?
On a one-way exam, the only place you can change your mind is inside the question, before you click Next. Common advice says never change your first answer. The research does not back that up. For decades, studies of multiple-choice exams have found that changed answers go from wrong to right more often than from right to wrong. A 2023 study of medical students found most of the class gained from changing answers, and the stronger students gained more. So the useful question is personal: when you switch, does it usually help you or hurt you? You can find out. For a few hundred practice questions, note your first pick and your final pick. Then count which way the changes went.
Learn the medicine, then train the decision
Review explanations properly. Ask why the right answer fits and why the others don't. When you miss a question, name the cause: missing knowledge, misreading the stem, wrong priority, running out of time, or a switch that didn't help. Different problems need different fixes. More questions won't fix a pacing problem.
Skip the recalls
Recall papers circulate in every IMG group. The AMC says it has reviewed these reconstructed papers and found many of the question stems and answers to be incorrect. Sharing or selling material that claims to be AMC exam content can also count as irregular behaviour under the AMC's rules.

The practical rule
Don't only ask, "How many questions have I done?" Ask, "What happens to my pace and my judgement in the last hour?" That is the part of the exam most preparation never touches.
