Most advice about how to split your IMAT study hours, including some of ours, treats the ratio as fixed: spend roughly this percentage of your time on Biology, this much on Chemistry, this much on the rest, and hold that same split from week one to the final week. That quietly ignores that the sections aren't all the same kind of thing to get good at.

The short answer: content sections (Biology, Chemistry, Physics & Maths, General Knowledge) can be front-loaded early in your prep and maintained with light review. Skill sections (Logic, Reading, data interpretation) can't - they need steady practice all the way to test day, or the speed you built decays.

Two different kinds of ability, not one

Biology, Chemistry, Physics & Maths, and General Knowledge are mostly content: specific facts, formulas, and concepts that either sit in your memory or don't. Logical Reasoning, Reading Comprehension, and the data-interpretation questions layered across every section are mostly skill: pattern recognition and reasoning speed built under a ticking clock. Content and skill don't behave the same way once you've built them, and a schedule that treats them identically is solving the wrong problem for at least one of them.

Why content can genuinely be front-loaded

Once you've learned a fact or formula well enough to recall it cold, it mostly needs occasional spaced review to stay in place, not continuous fresh study. That means the heaviest content sections are the right place to spend a disproportionate share of your early months, when the goal is building the base, and a shrinking share later, when the goal shifts to maintaining it with light review while your hours go elsewhere.

Why skill sections punish that same approach

Logical reasoning and reading comprehension don't bank the same way. The pattern recognition that makes you fast under time pressure decays if you stop practicing it, even for a couple of weeks, and cramming it back in during the final days rarely restores it in time. A candidate who front-loads these sections and then drops them for two months of pure content review often shows up on test day sharper on facts and noticeably slower on exactly the questions that reward speed - the data-interpretation skill buried in every section included.

What this actually looks like week to week

In practice, that means your first couple of months should lean hard into content, since that's where raw hours produce the most durable gain fastest. From the middle of your timeline onward, deliberately shift a growing share of each week toward logic, reading, and data-interpretation practice, even as your total content hours shrink to maintenance level. If you're mapping this onto an actual weekly structure, a realistic IMAT study week is the place to see what that balance looks like in practice. The ratio you start with and the ratio you end with should look different, and if they don't, you're probably either under-practicing the skill sections early or neglecting content review late.

Not sure how your own study ratio should actually shift as your timeline gets shorter? That's exactly the kind of individual calibration that's hard to get right from a generic schedule, and it's what 1:1 mentorship helps you build week by week.

Apply for the mentorship

There's no universal week where the switch should happen, since it depends on your starting level in each section. But the direction is the same for almost everyone: heavy on content early, heavier on trained skill late, not one static split held from the first week to the last.
