Study tips for MCAT

Use official AAMC materials

The AAMC offers official practice exams, question packs, and section banks. These are the most representative of actual test content.

Build content foundations first

Master the foundational sciences before diving into practice questions. Strong fundamentals make passage analysis easier.

Practice CARS regularly

The Critical Analysis and Reasoning Skills section requires consistent practice. Read challenging humanities passages daily.

Simulate test-day conditions

Take full-length practice tests under timed conditions to build stamina for the 7+ hour exam.

Review psychology and sociology

The Psych/Soc section is newer. Many premeds underestimate it. Use dedicated review materials for this content.
