There's no shortage of practice material online claiming to be IMAT-style. The quality varies a lot, and practicing against a badly calibrated mock can genuinely teach you the wrong instincts, not just waste time. The short version: official past papers are the gold standard, and any third-party source should be checked against them before you trust it.
The single most reliable source
Actual official past papers are the gold standard, since nothing replicates real question style, difficulty, and format better than the real exam itself. We've written separately about working through every past paper, and that remains the foundation any other practice material should sit on top of, not replace.
What to check before trusting a third-party source
Does it match the current section proportions and question count. Does it use a five-option format with a plausible, exam-realistic style of distractor, not obviously fake or absurd wrong answers. Does it come with a clear answer key and, ideally, explanations, not just answers with no reasoning shown.
A warning sign worth taking seriously
If a mock consistently feels dramatically harder or easier than real past papers, that's a signal the calibration is off, not necessarily that your level has changed. Scoring unusually high or low on one source compared to your performance on official past papers is worth noticing rather than taking at face value.
How to actually build a practice rotation
Prioritize official past papers first and treat them as your primary calibration point. Use well-regarded third-party mocks to supplement volume once you've exhausted official material, but keep checking new sources against your known baseline rather than assuming every source is equally trustworthy - and once you've got sources you trust, how often you actually sit them matters too.
Not sure whether the material you're currently practicing with is actually well-calibrated? That's a quick, useful thing to sanity-check with a mentor before you build months of practice around it.
