CARS Strategy: Passage Analysis & Question Types

Free MCAT study guide — Critical Analysis and Reasoning Skills

Reading Strategy

The 4-Step Approach

  1. Preview (10 seconds): Glance at passage length and topic. Don't read questions first.
  2. Read actively (3-4 minutes): Identify the main idea of each paragraph. Note the author's tone and argument structure.
  3. Identify the thesis: After reading, mentally summarize the author's main claim in one sentence.
  4. Answer questions (5-6 minutes): Return to passage for evidence. Eliminate wrong answers.
Key Point: CARS is about what the AUTHOR thinks, not what YOU think. Every correct answer is supported by the passage.

Question Types

TypeWhat It AsksStrategy
Main IdeaWhat is the author's central argument?Summarize thesis. Avoid too narrow or too broad.
Detail/RetrievalWhat does the passage state about X?Locate specific evidence. Paraphrase, don't match exact words.
InferenceWhat can be inferred / implied?Must be supported by passage. Strongest inference = most directly supported.
Strengthen/WeakenWhat would support or undermine the argument?Identify the author's claim, then find what helps/hurts it.
Author's Tone/AttitudeHow does the author feel about X?Look for loaded words, qualifiers, praise/criticism.
Function/PurposeWhy does the author mention X?Consider context. What role does this serve in the argument?
Application/AnalogyWhich scenario is most analogous?Abstract the principle, then match structure.

Common Traps

  • Extreme language: "always," "never," "all," "none" — usually wrong unless passage explicitly uses them
  • Out of scope: Brings in outside knowledge not in the passage
  • Opposite: Contradicts the passage — often a tempting distractor
  • Too narrow: Only covers one detail, not the main idea
  • Half right: Starts correct but ends with an unsupported claim
Key Point: When stuck between two answers: go with the one MORE DIRECTLY supported by the passage. The MCAT rewards conservative inference.

Timing

9 passages × 10 minutes each = 90 minutes total.

  • ~4 minutes reading + annotating
  • ~6 minutes answering 5-7 questions
  • Flag and return to difficult questions — don't spend 3+ minutes on one question
