What CARS actually tests
CARS is the only section with no content to memorize. It tests how you read arguments: what the author claims, how paragraphs relate, what is supported versus merely mentioned, and what follows from the passage.
Every wrong answer in CARS is wrong for a nameable reason: too broad, too strong, out of scope, half right, or contradicted by the passage. The section rewards students who review by argument rather than by feel.
Reading a 121 honestly
A 121 in CARS sits in the 15th 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
CARS improvement on a retake almost never comes from reading faster. It comes from neutralizing your two or three recurring wrong-answer habits, which you can only find by reviewing misses in writing and naming the pattern each time.
Official material matters most in CARS because no third party fully replicates AAMC answer-choice logic. The AAMC CARS Diagnostic Tool, used on a steady cadence, is the deepest pool of it.
