Mastering CARS

Part of The MCAT. CARS, or Critical Analysis and Reasoning Skills, is the section where you are asked to understand an unfamiliar passage and reason from it. You cannot memorize your way through it. You have to build the reading habit.

Why CARS is different

CARS gives you passages from the humanities and social sciences and asks you to reason about what you read. The passage may discuss philosophy, history, art, ethics, culture, or politics. You are not expected to arrive as an expert in those subjects. The information you need should be in the passage.

That sounds fair. It can still be difficult.

The section rewards understanding the author's argument, tracking the structure of the passage, and choosing the answer best supported by the text. It does not reward bringing in what you already know about the world or what you personally think about the subject.

CARS can be especially frustrating if English is not your first language, if you did not grow up reading dense prose, or if standardized reading tests were not part of your earlier education. That is an access difference, not a measure of your intelligence or your potential as a physician. It does mean you may need to give yourself time to build the skill.

The basic habit

CARS improves through regular practice. A short passage most days is usually more useful than doing a large number of passages once every few weeks.

You do not need to start with a full CARS section every day. Start with one passage, review it carefully, and build from there. Over time, practice should include timed sets and full sections so that reading skill and endurance develop together.

The goal is not to feel brilliant after every passage. Some passages will feel strange. The goal is to become less surprised by the work and more consistent in how you approach it.

How to read a passage

You will find many CARS strategies online. Some students annotate heavily. Some write only a few words. Some do not write anything. There is no universal annotation system that turns CARS into a predictable section.

Try to track four things as you read:

The main point. What is the author trying to say?
The structure. How does each paragraph move the argument forward?
The author's position. Is the author defending an idea, criticizing it, weighing multiple views, or changing direction?
The important turns. Where does the passage introduce a contrast, qualification, example, or conclusion?

You do not need to understand every historical reference or unfamiliar word. You need to understand what role that information plays in the argument.

At the end of the passage, pause for a few seconds and put the main point into your own words. If you cannot explain the passage's basic argument, jumping straight into the answer choices usually makes the next few minutes harder.

How to answer the questions

The right answer is the one the passage supports. That sounds obvious, but it is where many CARS questions become difficult.

For each question:

identify what the question is actually asking;
return to the relevant part of the passage;
eliminate answers that are too extreme, too vague, or outside the passage;
distinguish what the author said from what you believe; and
choose the answer that requires the fewest unsupported assumptions.

For an inference question, you are allowed to think beyond the exact words on the page. You are not allowed to invent a new argument that the passage never supports.

When two answers seem possible, ask which one the author would recognize as a fair description of the passage. The answer that is true in the real world may still be wrong if the passage does not support it.

Review is where the improvement happens

Completing a passage and checking the answer is not enough. The useful work starts after you miss a question or get one right by guessing.

For every miss or uncertain answer, ask:

What type of question was this?
What part of the passage supports the correct answer?
What made my answer attractive?
Did I misunderstand the passage, the question, or the answer choices?
Did I bring in outside knowledge or my own opinion?
Was my answer too extreme, too broad, or too narrow?

Keep a short record of the patterns. You might learn that you regularly miss questions about the author's tone, choose answers that go too far, or change your answer without a real reason. Those are problems you can work on. “I got it wrong” is not yet a diagnosis.

Do not spend twenty minutes trying to invent a theory for a question whose answer you simply misread. Be thorough enough to find the pattern, then move on.

Timing without panic

The CARS section gives you 90 minutes for 53 questions. ⟳ Verify the current format with the AAMC. That is enough time to work deliberately, but not enough time to get trapped by one passage.

During practice, notice where the time goes. Are you reading slowly? Spending too long on one question? Rereading because you lost the author's point? The solution depends on the problem.

Do not force yourself to read faster before you can understand what you are reading. Speed without comprehension is just a quicker way to choose the wrong answer. Build accuracy first, then let timing improve through repeated practice.

Full timed sections should come later, after you have practiced the basic work. If every early practice session is a frantic race, you may end up training panic instead of reasoning.

A practical progression

First phase: build the habit

Complete one passage several days a week. Read for the author's argument. Review every question you missed or guessed on. Do not worry yet about making every session look like test day.

Second phase: build consistency

Move toward regular timed sets of two or three passages. Keep looking for patterns in your misses. Try different levels of annotation and settle on the one that helps without slowing you down.

Third phase: simulate the section

Complete full timed CARS sections under realistic conditions. Review them the same day or the next day while you still remember your reasoning. Use the results to decide whether the problem is reading, timing, question analysis, or answer selection.

Final phase: use the most representative material

Save the official AAMC CARS material for the period when you need the clearest comparison to the real exam. Third-party passages can provide volume and help you build a habit. They do not all match the AAMC's style perfectly.

The resources

AAMC CARS materials

The AAMC CARS Diagnostic Tool and CARS Question Packs are the most important paid CARS resources because they come from the organization that writes the exam. The current Question Pack Bundle is listed around $76.50 on sale, with a regular price of $90.¹ The complete online bundle is listed around $323.70 on sale, with a regular price of $390. Eligible Fee Assistance recipients may receive official prep products at no cost. ⟳ Verify current pricing and access.

Use these for calibration and later practice. Do not spend them without reviewing the questions carefully.

Jack Westin

Jack Westin offers free daily CARS passages and additional practice. The free tier is $0. Jack Westin+ is currently $29.99 per month and adds more tools, solutions, and structure. ⟳ Verify current access and pricing.

The free daily passage is useful because it makes regular practice easy. I would use it for volume and habit-building, while keeping AAMC material as the reference point for what the real section feels like.

ExamKrackers 101 Passages

The ExamKrackers 101 Passages book is a paid option for additional CARS volume. New and used prices vary, but current listings commonly fall around $35–$50. ⟳ Verify the edition and price before buying.

It can be useful if you want a physical workbook and more passages. You do not need it if you already have enough practice or if the cost would strain your budget.

What not to do

Do not wait until the last month to begin CARS.
Do not spend all your time searching for the perfect strategy.
Do not memorize outside facts to prepare for the passages.
Do not treat a third-party score as a precise prediction of your AAMC score.
Do not review only the questions you got wrong. Lucky guesses are useful information too.
Do not assume a bad first diagnostic means you cannot improve.

CARS can be slow to improve. That does not mean practice is doing nothing. It may mean you are building a skill that is less visible than memorizing a list of facts. Keep an eye on your review patterns, not just one day's score.

Where this fits in the MCAT plan

CARS is a separate practice habit inside the larger Study Plan. It does not need to take over your entire week. A regular passage, careful review, and periodic timed sets are enough to make it part of the routine.

The Exam Blueprint explains the three CARS skills. The Resource Tier List compares CARS resources and their costs. The rest of the MCAT plan handles the science content, retention, and full-length practice around it.

CARS strategies, product availability, and prices change. Verify the current format and resource details with the AAMC and providers before planning around them. This page is educational information, not medical, financial, or admissions advice. — Last reviewed: 2026-08-06
