IMAT Math Topics: What Shows Up (And What Doesn't)

No calculus, barely any trigonometry - IMAT maths draws from a much narrower slice of the syllabus than most candidates assume. Physics & Maths gets treated as one blob of a section, but the two halves test genuinely different skills, and if you've been working through a general maths review instead of the specific handful of topics the IMAT actually leans on, you're probably spending hours in the wrong place.

What actually shows up

Percentages, ratios, and proportions appear constantly, often disguised as a chemistry or biology question rather than labeled as maths at all - a dilution calculation or a rate problem is a proportion question wearing a lab coat. Basic algebra shows up too, but almost always as solving for one variable or rearranging a formula, not multi-step manipulation. Powers, roots, and scientific notation get tested through conversion and estimation rather than heavy computation, and basic probability appears as single-event odds, not conditional trees. Reading and interpreting a graph or table gets filed under maths on paper, but it's really a data-literacy skill, and it shows up often enough to be worth practicing on its own.

What almost never shows up

Calculus is essentially absent - no derivatives, no integrals. Trigonometry rarely goes beyond knowing what sine, cosine, and tangent mean in a right triangle, and complex multi-step algebra doesn't fit the exam's format anyway, since every maths question needs to be answerable in roughly a minute. If you're deep into a calculus refresher or a trig identity workbook right now, that time is very likely better spent elsewhere.

Where the confusion comes from

Because maths is grouped with physics, and physics problems often require setting up an equation before you can solve anything, candidates assume the maths itself must be advanced to match. It usually isn't. The hard part in most Physics & Maths questions is the setup, working out which relationship applies, not the arithmetic that follows once you've set it up correctly.

How to actually prioritize your maths prep

Spend limited time on calculus or trigonometry beyond the basics unless you're already comfortable with them for other reasons. Put more of your hours into the "disguised maths" that shows up inside biology and chemistry data questions, since that's where proportion and estimation skills actually earn points. And drill mental estimation speed specifically - calculators aren't part of the exam, and the numbers involved are designed to be manageable by hand if you're fast with the basics.

The IMAT was never testing how far into a maths textbook you got. It's testing whether you can move fast and correctly through a small set of operations, over and over, under time pressure - and that's a much more learnable skill than most candidates treat it as.
