How Long to Wait Between IMAT Mock Exams

Most candidates ask how many mock exams they should take before the IMAT. Almost nobody asks how much time to leave between them, and it's arguably the more important question. Two people can sit the exact same ten mocks and come away with completely different results, depending entirely on what happened in the gaps.

The short answer: one full mock a week is plenty with several months left, tightening to at least two to three clear review days per mock as test day nears, and at least one full review session between each pair even in the final two weeks.

Why stacking mocks back to back feels productive and isn't

Booking three full-length mocks over one long weekend produces a satisfying pile of scores fast, and it feels like serious effort. But sitting a mock is just data collection. If you sit the next one before you've actually looked at what went wrong in the last one, you walk in carrying the same gaps forward and simply confirm them again, only now with less time left to do anything about it.

What actually needs to happen in the gap

A real review isn't skimming the answer key to see which letter was correct. It means sorting your wrong answers into actual patterns, going back to the specific topic behind each one, and doing a focused batch of practice questions on exactly that weak spot before you consider it closed - the process we walk through in how to actually review a mock exam. That process takes real hours, not minutes, and it can't be compressed into the twenty-minute gap between two exams sat on the same afternoon.

A spacing rule that scales with how much time is left

With several months of prep left, one full mock a week is plenty, leaving six or seven days for a proper review cycle plus normal content study. As you move into the final month, it's fine to tighten that, but try to keep at least two to three clear days after each mock before the next one, purely for review. In the last two weeks, when mocks get more frequent for stamina reasons, protect at least one solid review session between each pair rather than letting them blur into a single unreviewed streak.

When it's fine to break the rule

Not every mock needs a full review cycle behind it. A timed simulation you're running mainly to rehearse logistics, like pacing yourself under the real clock or practicing your section order, can sit closer to another one, since its job is to build exam-day reflexes rather than to surface new content gaps. Save the strict spacing rule for mocks you're actually treating as diagnostic.

More mocks isn't the same as more progress. The exam you learn the most from is rarely the tenth one you rushed into, it's the one you actually gave enough room to review properly first.
