MDCAT Chemistry

45 of 180 MDCAT questions

The same core ideas come up again and again. Once the fundamentals sit right, Chemistry becomes the most predictable section on the paper.

Chemistry is the second-biggest section, about 45 questions. Most of them lean on a small set of ideas: the mole concept, bonding, periodic trends, equilibrium, and the main organic reactions.

Very few questions need long calculations. What the paper really checks is whether you can apply a concept quickly. Students who lose marks here usually lose them in stoichiometry, not in some obscure chapter they skipped.

What’s covered in MDCAT Chemistry

  • Atomic structure & electronic configuration
  • Periodic table & trends
  • Chemical bonding
  • States of matter
  • The mole concept & stoichiometry
  • Thermochemistry
  • Chemical equilibrium
  • Acids, bases & pH
  • Electrochemistry
  • Organic chemistry — functional groups & reactions

How to prepare for MDCAT Chemistry

  • Mole concept first. It quietly sits inside half the numerical questions.
  • Write the periodic trends on one page and revise that page until it feels obvious.
  • For organic, learn functional groups and their reactions as families, then drill MCQs until you recognise them on sight.

MDCAT Chemistry: your questions

How many Chemistry questions are on the MDCAT?
About 45 of the 180, second only to Biology.
Is MDCAT Chemistry more conceptual or calculation-based?
Mostly conceptual. The calculations that do appear are single-step, and nearly all of them trace back to the mole concept or basic equilibrium.
How do I prepare for organic chemistry?
Functional groups. Learn what each one does and the reactions it undergoes, then practise until recognising them is reflex. Organic looks huge in the FSc book, but the MDCAT tests a fairly repetitive slice of it.

Next steps: once you know where Chemistry fits, see the MDCAT score you actually need with the aggregate & merit calculator, check the full syllabus, or fit it into a 6-week plan.
