Why a custom MCAT quiz beats hunting for answer keys

Many MCAT candidates searching for free MCAT practice test answers want a ready-made key to check their work. Official Kaplan practice tests and their answer keys are copyrighted, so a free copy posted online is often unauthorized and may be wrong.

Answers explain the reasoning, not just the letter
Questions come from your own notes and materials
Works with photos of pages through text recognition
Spaced repetition on paid plans for the topics you miss

Example MCAT practice questions with answers

Which molecules carry high-energy electrons from glycolysis and the Krebs cycle to the electron transport chain?NADH and FADH2. They deliver electrons to complexes in the inner mitochondrial membrane, which drives ATP production.

Which organelle modifies, sorts and packages proteins and lipids received from the endoplasmic reticulum?The Golgi apparatus. It prepares molecules for secretion or delivery to other organelles.

A 2 kg object experiences a net force of 10 N. What is its acceleration?5 m/s². Newton's second law gives a = F/m, so a = 10 N ÷ 2 kg.

Which brain structure is most associated with forming new long-term declarative memories?The hippocampus. Damage to it impairs the formation of new long-term memories while often leaving older ones intact.

Which amino acid is achiral because its side chain is a single hydrogen atom?Glycine. Without four different groups on its alpha carbon, it has no stereocenter.
