LSAT Reading Comprehension Guide

The scored LSAT has one Reading Comprehension section: 35 minutes, four passage sets, and roughly 27 questions (LSAC doesn't publish a fixed count). One of the four sets is usually a comparative reading set—two shorter passages, labeled Passage A and Passage B, with questions about how they relate. Passages come from areas like law, the natural sciences, the humanities, and the social sciences. LSAC says the section assesses your ability "to read and understand examples of long-form, complex materials which are similar to those that you'll encounter in law school."

RC is about a third of your scored questions—less than Logical Reasoning, but too much to wing. And because your unscored section can be RC, you might see a second RC section on test day without knowing which one counts.

You don't need background knowledge. Every answer is supported by the text; if you find yourself reasoning from what you already know about the topic, stop.

Most wrong answers in RC come from misreading the passage's structure, not from forgetting a fact. As you read, track four things:

1. Main point. What is the author ultimately claiming? Try to state it in one sentence when you finish.
2. Purpose of each paragraph. Jot three to six words per paragraph: "old view," "problem with old view," "new theory," "limits of new theory."
3. Viewpoints. Whose opinion is each claim? LSAT passages juggle critics, scholars, and the author. Many wrong answers attribute someone else's view to the author.
4. Author's attitude. Look for evaluative words—"unconvincing," "elegant," "has its own difficulties." Authors are rarely neutral, and rarely extreme.

Pay special attention to pivot words: but, however, yet, although, admittedly, in contrast, moreover. They mark the turns in the argument, and questions cluster around them.

The comparative set gives you two shorter passages on a related topic. The questions test the relationship between them more than the details of either one. Common stems:

• "Both passages are primarily concerned with…" (the shared topic—not one passage's main point)
• "The authors would be most likely to disagree about…" (both authors must take a position on it)
• "Which one of the following most accurately describes the relationship between the two passages?"
• "The author of Passage B would most likely respond to Passage A's claim that… by…"

How to read the pair: map Passage A normally. Then read Passage B asking one question the whole time—how does this relate to A? Does B agree, disagree, qualify, apply, or answer a different question? Write that relationship down in a few words before you touch the questions.

For much of the twentieth century, many professional historians treated oral testimony with suspicion. Memories fade and are reshaped by later experience, they argued, so an interview conducted decades after an event is a poor guide to what actually happened. Written records, created at the time, seemed more trustworthy.

Practitioners of oral history have answered this objection in two ways. First, they point out that written records are not neutral either: a government report or a company ledger reflects what its authors chose to record and whom they hoped to persuade. Second, and more interestingly, they argue that the distortions of memory are themselves evidence. When a community consistently misremembers the date of a strike—placing it in the year of a later, more painful layoff—the error reveals how that community understood its own history, something no ledger could show.

Question 1: The primary purpose of the passage is to…

Answer: describe an objection to the use of oral testimony and explain how oral historians have responded to it. That covers both paragraphs. A tempting wrong answer—"argue that written records are less reliable than oral testimony"—overstates the first response, which says only that written records aren't neutral either.

Question 2: The example of the misremembered strike serves primarily to…

Answer: illustrate how a distortion in memory can itself provide historical insight. It's attached to the "second, and more interestingly" response. The trap is "show that oral testimony is often inaccurate"—the example does involve an inaccuracy, but the author uses it to show what the inaccuracy reveals, not to concede the skeptics' point.

Notice what made both questions easy: knowing the passage's structure (objection → two responses → example supporting the second), not memorizing its details.

• Extreme wording: "always," "proves," "refutes," "only"—LSAT authors usually hedge.
• Wrong viewpoint: a view the author describes but doesn't hold, presented as the author's view.
• True but irrelevant: a choice the passage supports that doesn't answer this question.
• Half right: the first half matches the passage; the second half adds something it never says.
• Too narrow: on main-point questions, a choice that captures one paragraph only.
• Outside knowledge: a choice that's true in the real world but not supported by the text.

Thirty-five minutes for four sets is just under nine minutes per set, including reading. A common split is about three to four minutes to read and map, then the rest for questions. If one passage is eating your time, answer its remaining questions with your best guesses, flag them, and move on—no single set is worth sacrificing the rest of the section for, and there's no penalty for wrong answers. Some people prefer to start with the passage topic they find easiest; if you do, make sure the order switching doesn't cost you more time than it saves.

1. Week 1 — Mapping. Read one official passage a day untimed. Write the main point and a note for each paragraph before looking at any questions.
2. Week 2 — Question types. Answer questions with your map. For every miss, label the question type and the trap you fell for.
3. Week 3 — Comparative sets. Do several comparative sets, writing the A–B relationship in a few words before answering.
4. Week 4 — Timing. Take full 35-minute RC sections and blind-review them. Track whether your misses come from reading (wrong map) or answering (right map, wrong choice).
