How CARS works
Critical Analysis and Reasoning Skills is the second section on test day: 53 questions in 90 minutes, all built on passages of roughly 500–600 words. You get about 10 minutes per passage, including the questions.
- No outside knowledge. AAMC says no additional coursework or specific knowledge is required; everything you need is in the passage. Knowing the topic can actually hurt if it tempts you to answer from what you know instead of what the author said.
- Half humanities, half social sciences. AAMC splits passages 50/50 and draws them from ethics, philosophy, studies of diverse cultures, population health, and a wide range of other humanities and social science disciplines. The writing is dense and deliberately sophisticated.
- Authors argue. Most passages have a point of view, often pushing back against a common opinion. Finding that stance is half the battle.
The three skills CARS tests
| Skill (AAMC) | Share | What it looks like |
|---|---|---|
| Foundations of Comprehension | 30% | Main idea, specific details, meaning of a word or phrase in context, the author's tone |
| Reasoning Within the Text | 30% | Why the author includes a claim or example, how two ideas relate, how well a claim is supported |
| Reasoning Beyond the Text | 40% | Applying the author's ideas to a new situation, and judging how new information would strengthen or weaken the argument |
The biggest slice is Reasoning Beyond the Text. That's why pure "find it in the passage" reading isn't enough: you have to understand the author's logic well enough to extend it.
A passage strategy that holds up at 10 minutes
- Read the whole passage once, at a steady pace (about 3–4 minutes). Don't skim the questions first; most CARS questions depend on the overall argument, not a single line.
- Track the author, not the facts. After each paragraph, ask: what is this paragraph doing—setting up a view, attacking it, giving an example, conceding a point? One-line mental notes are enough.
- Find the pivot words. But, yet, however, in fact, the problem is, I want to resist. The author's real claim usually comes right after one.
- State the main point before you start the questions. One sentence: "The author thinks X, not Y, because Z." If you can't, reread the first and last paragraphs.
- Answer each question by predicting first. Form a rough answer before reading the choices, then pick the choice that matches. This defuses attractive distractors.
- Budget the questions (about 6 minutes). If a question is eating more than 90 seconds, pick your best choice, mark it, and move on.
Question types, with an original example
Here's a short original excerpt in CARS style (real passages are about five times longer):
Museums like to present their collections as windows onto the past. But a window is transparent, and a museum is not. Every label, every choice about which object sits at eye level and which stays in storage, is an argument about what the past means. Visitors who believe they are simply looking are being persuaded without knowing it. The remedy is not to abandon curation, which is impossible, but to make its choices visible—to let visitors see the argument so they can disagree with it.
Foundations of Comprehension — main idea. The author's central claim is that museums… Prediction: museums unavoidably shape interpretation and should make those choices visible. Trap: "museums should stop curating their collections"—the author calls that impossible.
Reasoning Within the Text — function. The author contrasts a window with a museum in order to… Prediction: challenge the idea that museums are neutral. The window image is the view being attacked, not the author's view.
Reasoning Beyond the Text — application. Which exhibit would the author most likely praise?
- A) An exhibit with no labels, so visitors can form their own impressions
- B) An exhibit that displays only the museum's most valuable objects
- C) An exhibit with panels explaining why curators chose these objects and what they left out
- D) An exhibit arranged strictly by date, to avoid any interpretation
Answer: C. It makes curatorial choices visible. A and D are tempting because they seem neutral, but the author's whole point is that no arrangement is neutral—removing labels or sorting by date is still a choice, just a hidden one.
Reasoning Beyond the Text — strengthen/weaken. Which finding would most weaken the argument? Look for something that attacks the key link: here, evidence that visitors' interpretations aren't affected by labels or placement would undercut "being persuaded without knowing it."
The wrong answers CARS loves
- Too extreme. "Always," "never," "abolish," "proves." Authors in CARS are usually more measured than the choices that misrepresent them.
- The opposing view. Many passages describe a position before attacking it. Choices that restate the attacked view are a classic trap.
- True but off-target. A choice that matches a sentence in the passage but doesn't answer this question.
- Half right. The first half of the choice is great; the second half adds a reason or claim the passage never makes. Read to the period.
- Your own opinion. If you'd need outside knowledge or personal belief to justify a choice, it's probably wrong.
How to practice CARS
- Daily, timed, and reviewed. Two or three passages a day beats a marathon on Sunday. Time each passage at 10 minutes.
- Review every question, including the ones you got right. For each, write one line on why the right answer is right and why your runner-up is wrong. Guessing right doesn't mean you understood it.
- Use official passages as your benchmark. AAMC's CARS material—the CARS sections of its seven full-length exams (the Unscored Sample Test and Practice Exams 1–6; the first two are free) and its new CARS Question Bank—reflects the real test's logic better than any third-party passages. Save some of it for the final weeks.
- Read dense stuff outside of prep. Long-form essays in philosophy, history, and the arts build the stamina CARS demands.

ReadFrequently asked questions
Can you improve your CARS score?
Yes, but it tends to move slowly because you're building a skill, not adding facts. Consistent daily practice with careful review is what works; cramming doesn't.
Should I read the questions before the passage?
Usually not. Most CARS questions test the overall argument, and previewing questions eats time without telling you much. Read the passage once, carefully, then answer.
Should I highlight or take notes on CARS passages?
Keep it light. Marking the author's main claim and the pivot words helps; marking half the passage doesn't. Practice with AAMC's free Unscored Sample Test, which has the same look and feel as the real exam, so the tools feel familiar on test day.
How long are CARS passages?
Roughly 500–600 words each. With 53 questions in 90 minutes, plan on about 10 minutes per passage, including the questions.
Do I need background knowledge in philosophy or art?
No. AAMC designs CARS so that all needed information is in the passage. Familiarity with dense academic writing helps with speed, but outside facts shouldn't drive your answers.
