LSAT Question Type Frequency: How Often Each Type Appears

How often does each question type appear on the LSAT®? Most frequency analyses hand-classify thousands of questions into one prep company’s taxonomy, which introduces error at every step. We counted something simpler: the categories LSAC itself prints on score reports, across 30 PrepTests (PTs 130–159).

Logical Reasoning frequency

Each scored LSAT® contains two Logical Reasoning sections of roughly 26 questions each. The table below shows how those questions distribute across LSAC’s nine score-report categories.

Source: 60 scored LR sections and 30 scored RC sections across 30 PrepTests (PTs 130–159). Values blended 60% recent / 40% all, rounded to nearest 0.25.

Reading Comprehension frequency

Each scored LSAT® contains one Reading Comprehension section of roughly 27 questions. The table below shows how those questions distribute across LSAC’s seven RC categories.

Methodology: why we used grouped categories

LSAC score reports always use the same nine grouped LR categories regardless of which PrepTest you take. We verified this across PTs 130–159: every single score report uses the same category labels and groupings. These are the categories that actually appear on your score report, the unit of measurement LSAC uses to tell you where you’re strong and where you’re not.

We observed the frequency data directly from these 30 PrepTests rather than deriving sub-type estimates. This matters because fine-grained breakdowns (like how often Necessary Assumption appears versus Sufficient Assumption) would require either hand-classifying every question or relying on a third-party taxonomy. Both introduce error.

The trade-off is that you don’t get sub-type granularity from this analysis. If you want to know what each grouped category contains (which individual question types roll up into "Assumptions" or "Techniques, Roles, and Principles"), see our question type conversions guide. That guide maps every fine-grained type to its score-report group and across all five major prep company frameworks.

What this means for your study plan

The big three LR categories (Assumptions, Flaws, and Strengthen or Weaken) represent roughly 46% of every scored section. If you’re weak in any of these, that’s your highest-impact study target. Improving your accuracy on types that appear 4 times per section moves your score far more than perfecting types that appear once.

On the other end, Matching Flaws and Matching Structure and Principles together account for only about 8% of a scored LR section. These are important, and they’re often the hardest questions on the test, but they’re a poor use of time if your fundamentals on the high-frequency types aren’t locked down yet.

In Reading Comprehension, inference questions at roughly 28% are the single biggest opportunity. They’re also the RC type that rewards the same close-reading and logical deduction skills you build in LR. Time spent on inference technique carries over to both sections.

Frequency is only half of it, though. A type that appears 8 times per test but you get right 90% of the time matters less than one that appears 4 times but you miss half. Impact equals frequency multiplied by miss rate. That’s the calculation ScoreGap’s prescriptive recommendations use to rank your study targets.

This data powers your ScoreGap recommendations

The frequency data in this guide is the same data feeding ScoreGap’s ROI engine. When your Score Report says "Flaw questions are your biggest opportunity," that’s prevalence from the tables above multiplied by your personal miss rate from your practice tests. The result is a prioritized list of exactly where your study time will produce the most points.

Your ScoreGap dashboard runs this calculation automatically after every practice test you import. The frequency data is the constant; your performance data is the variable.
