Sample Medical College Admission Test questions

These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

1. 1 Easy

   In MCAT biology, which organelle is the primary site of ATP production?

   Answer: Mitochondria

   Why: They keep their own circular DNA, a leftover from the free living bacteria that early cells swallowed and never digested.

2. 2 Medium

   In MCAT chemistry, what shape is a molecule with four bonding pairs?

   Answer: Tetrahedral

   Why: The pairs spread as far apart as possible, giving methane bond angles of 109.5 degrees; a lone pair would squeeze that angle smaller.

3. 3 Hard

   Which MCAT section requires no prior knowledge of any science topic?

   Answer: Critical Analysis and Reasoning Skills

   Why: Its passages are split evenly between the humanities and the social sciences, and everything needed to answer sits in the text.

4. 4 Easy

   What is the highest possible total score on the modern MCAT?

   Answer: 528

   Why: Each MCAT section is scored on a scale from 118 to 132, so a 528 means hitting the ceiling on every single section.

5. 5 Medium

   In MCAT physics, what is the SI unit of magnetic field strength?

   Answer: Tesla

   Why: Strictly it measures flux density, one weber per square metre; Earth's own field is a mere 25 to 65 microtesla, while MRI magnets reach several tesla.

6. 6 Hard

   In MCAT biology, which hormone increases water permeability in collecting ducts?

   Answer: Antidiuretic hormone

   Why: Also known as vasopressin, it slots aquaporin water channels into the collecting duct wall, so water can cross back into the body.
