What P/S actually tests
P/S covers psychology, sociology, and the biological bases of behavior. It has the largest vocabulary of any section: hundreds of named terms, theories, and thinkers, tested through research-style passages.
The classic P/S miss is choosing a term that is close but not exact. The section rewards precise definitions and the ability to match a study description to the concept it illustrates.
Reading a 121 honestly
A 121 in P/S sits in the 10th percentile on the official AAMC section table, in the lower part of the 118 to 132 scale. If this section pulled your total score down, that is frustrating, and it is also useful: it tells you exactly where a retake's points are most available.
A section score in this range usually reflects a fixable combination of gaps and execution rather than a ceiling. The plan matters more than the panic.
How Retakers move this section
P/S improvement on a retake is often the most direct of the four sections: close the vocabulary gaps with spaced repetition, then drill official passages so the terms connect to how the AAMC actually tests them.
Precision matters more than coverage. Reviewing why a near-miss term was wrong teaches more than another pass through a 300-page content review.
