The distractors are the exam
A well-written multiple choice question is not testing whether you know the answer. It is testing whether you can tell the answer apart from three things that a student with a shallow understanding would find equally plausible. The wrong options are written *specifically* to catch the common misconception.
Which means the skill being tested is discrimination, and the way to train discrimination is interleaving — mixing confusable topics until you can separate them — not reading each topic in isolation where nothing looks like anything else.
Revise by producing, test by choosing
- Cover the options. Read the stem, answer from memory, *then* look. If you can't answer with the options covered, you don't know it — you were about to recognise it.
- For every wrong option, say why it's wrong. This is the single highest-yield MCQ habit there is. Three explanations per question instead of one.
- Card the distractors, not just the answers. The misconception the examiner was fishing for is worth a card of its own.
- Use free-recall formats in revision — blurting, short-answer questions — even though the exam is MCQ. Train harder than you'll be tested.
In the exam itself
- Answer before you read the options wherever you can. It immunises you against the plausible distractor.
- Read every option anyway, even after you've found one you like. 'Best answer' formats punish stopping early.
- Watch the absolutes. Always, never, all, none — they are more often wrong than right, though this is a tiebreaker, not a strategy.
- Don't change an answer without a reason you can articulate. 'It feels wrong now' is anxiety, not information. A specific realisation is.
