How to use AMC CAT MCQ practice questions

Why questions are the centre of preparation

The CAT MCQ does not ask candidates to reproduce knowledge. It asks them to decide what to do for a patient described in a short clinical scenario. Reading alone rarely builds that ability, because reading rehearses recognition and the examination tests choice under time.

Practice questions do three things that reading does not. They force a decision, they expose which distinctions you hold securely, and they train the pace of about 84 seconds a question that the exam requires. The exam format guide describes that timing in full.

To try questions now, the free AMC CAT MCQ mock test has 15 timed questions under the exam's no-going-back rule, with an explanation for every option and no account needed.

Anatomy of a CAT MCQ question

The AMC describes each question as having one correct response from five options, and other options may be partly correct. Every question has the same three parts.

1. The scenario. A patient with an age, a setting, a presenting complaint, relevant history, examination findings and often investigation results. Some questions include an X-ray, ECG, scan or clinical photograph. Nothing in a well-written scenario is decoration. The setting in particular is usually load-bearing: a rural hospital, a general practice and a tertiary emergency department imply different options.
2. The lead-in. One specific question. Most likely diagnosis, most appropriate next investigation, most appropriate management, most likely causative organism. The lead-in decides which of the plausible options is right.
3. Five options. One is the correct response. The others are typically correct but premature, correct but for a different presentation, standard in another health system but not in Australia, or plainly wrong.

A worked example

Consider a scenario describing a 58-year-old man at a small rural hospital with 40 minutes of central chest pain, an ECG showing ST elevation across the anterior leads, no contraindication to fibrinolysis, and a catheter laboratory three hours away by road with no aircraft available for at least two hours. The lead-in asks for the most appropriate next step.

The options might include transfer alone, fibrinolysis followed by transfer, waiting for a troponin result, oxygen and nitrates with reassessment, and intravenous beta blockade with overnight observation.

Four of those are recognisable interventions in acute coronary syndrome, and three of them appear in the management of the condition somewhere. Only one answers the question asked, for this patient, in this place. Primary angioplasty is preferred when it can be delivered promptly; here it cannot, so reperfusion is achieved with fibrinolysis and transfer follows. The troponin option fails because ST elevation already calls for emergency reperfusion and waiting costs myocardium. The oxygen and nitrate option fails because neither reperfuses the artery.

That is the shape of most CAT MCQ questions. The clinical knowledge required is not obscure. The work is in noticing which single detail, here the travel time, decides between two otherwise reasonable answers.

Reviewing a question properly

Most of the value in a practice question is released after it is answered, and most candidates stop at the answer.

• Read the rationale for all five options, not only the one you chose. The four wrong options are where the examinable distinctions live.
• Say why your answer failed. Knowledge gap, misread detail, right principle applied too early, or practice from another health system. The four causes need different remedies.
• Record the principle rather than the question. Writing down "fibrinolysis when angioplasty cannot be delivered in time" transfers. Writing down the answer to question 47 does not.
• Return to the mistakes. A question answered wrongly and never seen again has taught nothing. This platform keeps every wrong answer and returns it in later sessions until it is answered correctly.

Recall questions

Recall questions are questions that previous candidates have written down from memory after sitting and circulated informally, often in compilations of varying age and accuracy. Candidates search for them because they promise the real thing.

There are good reasons not to build preparation on them.

• They are unreliable. A question reconstructed from memory loses the precise wording, and in a five-option question the precise wording is what separates the options. Remembered answers are frequently wrong.
• They are out of date. The AMC adds new questions to its pool, and Australian guidance is updated on its own schedule.
• They teach the wrong skill. Memorising the answer to a remembered question builds recognition of that question rather than the reasoning that would handle an unfamiliar one, and each candidate sits a customised exam.
• They carry a conduct risk. The AMC prohibits recording, disclosing or selling examination content, and it may withhold results where analysis suggests prior knowledge of questions.

Questions written to the format, reviewed against current Australian guidance and supplied with a rationale for every option do the job that candidates hope recalls will do, without those problems. The AMC's own material is the place to check scope: its free book Australian Medicine in Context lists the presentations and topics it describes as a guide to what is examinable, and its preparation app, built with eMedici, has 210 questions and comes free for 12 months with the CAT MCQ authorisation.

Building practice into a week

Use untimed questions while a patient group is still new, so that each one can be read slowly and reviewed fully. Move to timed mixed sets once the material is familiar, because switching between specialties under a clock is the specific demand of the exam, where questions are randomised across the blueprint. Add full timed mocks in the final weeks to test stamina across three and a half hours.

The free diagnostic samples every patient group and gives a first read on every subject. The free mock test and the sample questions show the format with full explanations before any account is created.
