What the MCAT CARS Section Actually Tests
MCAT CARS uses no outside knowledge — it tests reading and reasoning alone. Learn what the section measures, its two question families, and why pre-meds find it uniquely hard.

CARS in one paragraph
The Critical Analysis and Reasoning Skills (CARS) section of the MCAT presents passages from the humanities and social sciences and asks questions about them. Crucially, it tests no outside content — everything you need is in the passage. CARS measures how well you comprehend an argument, analyze its reasoning, and apply or extend its ideas.
That is why strong science students sometimes struggle: CARS does not reward recall. It rewards careful reading and disciplined reasoning, the same muscles tested by LSAT Reading Comprehension and GRE verbal.
The two big question families
Comprehension: questions about what the passage says and means — the main idea, the author's tone, the meaning of a phrase in context.
Reasoning beyond the text: questions that ask you to apply the author's argument to a new situation, or to judge how new information would strengthen or weaken it. These are the hardest, because the answer is not stated in the passage.
Why pre-meds find CARS hard
The passages are deliberately dense and often on unfamiliar topics — philosophy, ethics, art criticism, history. There is no formula to memorize. And the timing is tight: roughly 90 minutes for nine passages and 53 questions, which leaves little room to reread.
The encouraging part: because CARS is a skill rather than a body of facts, it responds to deliberate practice. Reading argument-first and tracking the author's view is exactly the habit Verbloom builds.
How to start improving
Read for the author's main point and attitude before you touch the questions. Resist bringing in your own opinions or background knowledge. Practice with timed passages so the pacing becomes natural, and review every miss to see whether it was a comprehension slip or a reasoning slip. Those two error types need different fixes.
Frequently asked questions
Does CARS require any science knowledge?
No. CARS draws on humanities and social-science passages and tests only reading comprehension and reasoning. Every answer is supported by the passage itself, not outside facts.
How long is the CARS section?
CARS is about 90 minutes for 53 questions across nine passages — roughly ten minutes per passage including its questions.
Why do strong science students struggle with CARS?
Because CARS rewards careful reading and reasoning rather than memorized content. It is a skill that improves with deliberate, reviewed practice rather than study of facts.
