MCAT psychology and sociology: the Psych/Soc section

Psych/Soc is the last section of the day: 59 questions in 95 minutes. About 65% is introductory psychology, 30% introductory sociology and 5% introductory biology. MCAT psychology also leans on biology in places: the AAMC says about 5% of the section is biologically relevant psychology, on top of the biology share.

How much psychology is on the MCAT?

This is the only section that lists psychology or sociology. The AAMC rounds the figures to the nearest 5%, and they vary from test to test.

SubjectShare of Psych/Soc
Introductory psychology65%
Introductory sociology30%
Introductory biology5%

The content categories

The category pages name the areas but not every theory. Foundational Concept 9, for example, refers to basic sociological theories without naming them. The topic lists are in the AAMC outline.

Foundational concept (share)Content categories
6 (25%)6A Sensing the environment; 6B Making sense of the environment; 6C Responding to the world
7 (35%)7A Individual influences on behavior; 7B Social processes that influence human behavior; 7C Attitude and behavior change

9 (15%)9A Understanding social structure; 9B Demographic characteristics and processes
10 (5%)10A, on social inequality: social class, stratification, social mobility and poverty

Where to practice Psych/Soc

The AAMC doesn’t sell a separate psychology or sociology question pack; its packs cover biology, chemistry and physics. Its Psych/Soc practice comes in the full-length exams and the two Section Banks, which have 100 Psych/Soc questions per volume. The Independent Question Bank adds 25 psychology and 25 sociology questions.
