MCAT CARS Basics
CARS is 9 passages, 53 questions, and 90 minutes — with zero outside knowledge required.
CARS stands for Critical Analysis and Reasoning Skills, the one MCAT section with no science content at all. Every answer is derivable from the passage in front of you. This page covers the structure — passage count, question count, section length, scoring — and the question types that decide your score.
- CARS has 9 passages and 53 questions in 90 minutes — about 10 minutes per passage.
- It is scored 118-132 like every other section and contributes a quarter of your total score.
- No outside knowledge is tested. Bringing in your own facts is the most common CARS error.
Structure
The exact structure of the CARS section.
CARS is the second section on test day, sitting between Chem/Phys and your first optional break. Its structure has been stable for years.
- 9 passages, each roughly 500-600 words.
- 53 total questions, with 5-7 questions attached to each passage.
- 90 minutes total, with no discrete standalone questions.
- Sources are humanities and social sciences: philosophy, ethics, literature, history, cultural studies.
There are no science passages in CARS. Any technical term you meet is defined in the passage itself.
Timing
How much time to spend per CARS passage.
The clean split is about 10 minutes per passage: roughly 3-4 minutes reading and 6-7 minutes answering. Falling behind early is what causes the final-passage collapse.
- Target 10 minutes per passage including its questions.
- Check the clock after passage 3 (should be near 30 minutes) and passage 6 (near 60).
- Never leave a question blank — there is no penalty for wrong answers.
- Consider a deliberate throwaway passage if you consistently run out of time.
Question Types
The three question categories CARS uses.
The AAMC groups CARS questions into three skills. Recognizing which one you are looking at tells you how far beyond the text you are allowed to go.
- Foundations of Comprehension (~30%): what the author said and what a word or phrase means in context.
- Reasoning Within the Text (~30%): the author's argument, tone, and how claims are supported.
- Reasoning Beyond the Text (~40%): applying the author's reasoning to a new situation or judging new information.
Answer choices that are true in reality but unsupported by the passage are the single most common CARS trap.
Scoring
How CARS scoring works and what a good score looks like.
Your 53 raw answers convert to a scaled 118-132 score. Because the section is short, each raw question moves the scaled score more than in other sections.
- 118-132 scaled, with 125 as the approximate median.
- 128+ is a strong CARS score for competitive applications.
- A handful of raw questions can shift your scaled score by a full point or more.
- Many admissions committees look specifically at CARS as a reading-and-reasoning signal.
