What C/P actually tests
C/P covers general chemistry, physics, organic chemistry, and biochemistry as they apply to living systems. Passages are frequently experiment-based, and many questions ask you to set up and estimate calculations without a calculator.
The section rewards two distinct skills: content fluency (knowing the relationships) and quantitative rhythm (setting up problems quickly and estimating cleanly under time pressure). Students often have one without the other.
Reading a 120 honestly
A 120 in C/P sits in the 9th 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
C/P improvement on a retake usually starts with separating calculation misses from reasoning misses. A wrong setup means a content fix. A right setup with a wrong final choice usually means a trap or units slip, which is a different kind of practice entirely.
Mental math is trainable and high-yield here. So is drilling official material: the AAMC Chemistry Question Pack for volume and the C/P Section Bank for the reasoning-heavy top end.
Common questions
Is a 120 C/P score good?
A 120 in C/P is in the 9th percentile on the official AAMC section table, meaning 9% of section scores were equal to or lower. Whether it is strong enough depends on your total score, your section balance, and your target programs.
What percentile is a 120 in C/P?
On the AAMC section percentile table in effect May 1, 2026 to April 30, 2027, a 120 in C/P is in the 9th percentile.
How do Retakers improve C/P?
C/P improvement on a retake usually starts with separating calculation misses from reasoning misses. A wrong setup means a content fix. A right setup with a wrong final choice usually means a trap or units slip, which is a different kind of practice entirely.

Section scores only mean something in context. For scale, a 120 across all four sections would land near a 480 total. Compare nearby C/P scores: a 119 in C/P and a 121 in C/P, or see how a 120 reads in the other sections: CARS · B/B · P/S.
