One of the most essential pieces of knowledge you will need in order to perform well on the Biological and Biochemical Foundations of Living Systems section of the MCAT is the 20 amino acids. It is critical to learn the one-letter and three-letter amino acid abbreviations, as well as which group they fall into (positively charged, negatively charged, aromatic, polar or non-polar).

The amino acid quiz app is one of the best ways to memorize the amino acids using the method of active recall. You can choose personalized quizzes that test you on which aspects you are specifically trying to memorize, as well as track your progress in the app.

The Amino Acid Quiz app is available for free on both the app and google play stores. There is no desktop version of the app so you will need a smartphone or tablet to download the app.
