BIOLOGY

Biology carries the single largest weight in the entire MDCAT — 45% of the exam, 81 out of 180 MCQs. No other subject comes close. This alone makes Biology the subject where your preparation decisions matter most: a strong Biology score can carry your overall result, while gaps here are the hardest to make up elsewhere.

Biology across 16 chapters — from Biological Molecules and Cell Structure through Circulation, Immunity, Inheritance, and Biotechnology — is also uniquely demanding in how it needs to be studied. It isn’t just memorization; the real exam consistently tests how concepts connect to each other, not just isolated facts in isolation.

That’s exactly what our Biology question bank is built for. Nearly 2,000 MCQs, covering every chapter in full — not just what the curriculum explicitly names, but everything genuinely connected to it, based on real cross-checking against actual past MDCAT papers. Every question comes with a full explanation for all four options, so you’re not just memorizing the “correct” answer — you’re understanding exactly why the other three are wrong, which is often where the real learning happens.

With Biology worth nearly half your total score, walking into the exam confident here isn’t optional — it’s the difference-maker. That’s what this practice set is built to give you.
