ExploreAbout this exam
The Medical College Admission Test (MCAT) is the standardized exam the AAMC administers for people preparing to apply to medical school. Per the AAMC, it "assesses your knowledge of natural and social sciences concepts and your critical thinking and scientific problem-solving skills required to begin the study of medicine," and about 95,000 people take it each year. This page covers the Psychological, Social, and Biological Foundations of Behavior section - the psych/soc portion - with original practice questions built around four foundational concepts: how we sense and perceive the world and respond to it; factors influencing behavior and behavior change; how we think about ourselves and others; and social stratification and access to resources. The AAMC's "Take the MCAT Exam" page does not publish section-level item counts, timing, or content-category weights, so practice sets here are modular: drill one concept at a time or run mixed sets. The exam is offered multiple times a year from January and March through September at hundreds of test sites in the United States, Canada, and around the world, and registration is open for all January–September 2027 dates. This is an independent study resource and is not affiliated with or endorsed by the AAMC.
What you'll study
About MCAT Psych/Soc preparation
What does the MCAT actually test?
The AAMC describes the exam as assessing knowledge of natural and social sciences concepts plus the critical thinking and scientific problem-solving skills required to begin the study of medicine. Psych/soc is one portion of that broader test, so practice here should be paired with the official content outline rather than treated as the whole exam.
When is the MCAT offered, and can I register now?
According to the AAMC, the exam is offered multiple times a year from January and March through September at hundreds of test sites in the United States, Canada, and around the world. Registration is currently open for all January–September 2027 exam dates.
How many questions are on the section, how long is it, and what does it cost?
Those figures are not stated on the AAMC page this guide is based on, so we do not publish them. Check the MCAT Essentials publication for the current testing year and the MCAT FAQs for registration and fee details before you build a timing plan.
Can I retake the exam, and how many times?
The retrieved AAMC source does not state a retake policy, so no attempt limits or waiting periods are listed here. Confirm current rules in the MCAT Essentials and the official MCAT FAQs, since policies are set by the AAMC and can change between testing years.
How hard is the psych/soc section?
Difficulty is largely about precision, not obscurity. The section rewards exact use of terminology and the ability to apply concepts to unfamiliar passages, so students who memorize definitions without practicing application tend to plateau. Treat each missed question as a vocabulary or reasoning gap and log which one it was.
In what order should I study the four foundational concepts?
The AAMC does not publish content-category percentage weights on the source page, so there is no official order and no basis for prioritizing one concept by exam frequency. Start with a mixed diagnostic set, then spend the most time on whichever concept produces your lowest accuracy.
What are the most common ways candidates lose points?
Three recurring patterns: memorizing terms without practicing passage application, skimming research-methods and study-design details embedded in passages, and studying only in the format you like rather than the format you will face. Mix timed and untimed sets, and review every explanation even when you answered correctly.
What official preparation materials exist?
The AAMC links an MCAT Official Prep Hub, a "What's on the MCAT Exam?" outline, the MCAT Essentials, and score information through the Score Reporting System. Use the official outline to define scope, then use third-party question sets like these for volume and explanation depth.
I have a disability or medical condition. What should I do?
The AAMC encourages examinees who believe a disability or medical condition requires an adjustment to standard testing conditions to apply for accommodated testing. Apply through the MCAT Accommodations System well ahead of your target date, since approval must be in place before you schedule.
Is financial help available for the exam?
The AAMC maintains a Fee Assistance Program, linked from its MCAT pages, that provides reduced or waived fees to eligible applicants. Eligibility rules and award levels are set by the AAMC and are not detailed on the page this guide draws from, so verify current terms before registering.
