LSAT Question Type Frequency: How Often Each Type Appears
Data-driven breakdown of how often each question type appears on the LSAT, measured from 30 PrepTests using LSAC's own scoring categories.
How often does each question type actually appear on the LSAT®? Most frequency analyses try to break data down into individual prep-company categories, which requires hand-classifying thousands of questions or making assumptions about how grouped types split. We took a different approach: we measured what LSAC actually reports on score reports. We stayed true to LSAC’s own scoring categories and did not try to do gymnastics translating them into any one prep company’s taxonomy. We just looked at the frequency of the scored categories across time.
The result is a clean, verifiable dataset drawn from 30 PrepTests (PTs 130–159). No hand-classification, no guesswork about sub-type splits, no mapping to a third-party system. Just the categories LSAC uses on your score report, measured directly. Here’s what we found.
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.
| Category | Per Section (~26 Qs) | Per Test (×2 sections) | % of Section |
|---|---|---|---|
| Assumptions | 4.0 | 8.0 | 15.4% |
| Flaws | 4.0 | 8.0 | 15.4% |
| Strengthen or Weaken | 4.0 | 8.0 | 15.4% |
| Techniques, Roles, and Principles | 3.75 | 7.5 | 14.4% |
| Deductions and Inference | 3.5 | 7.0 | 13.5% |
| Explain or Resolve | 2.0 | 4.0 | 7.7% |
| Conclusions and Disputes | 2.0 | 4.0 | 7.7% |
| Matching Flaws | 1.0 | 2.0 | 3.8% |
| Matching Structure and Principles | 1.0 | 2.0 | 3.8% |
The top three categories (Assumptions, Flaws, and Strengthen or Weaken) make up roughly 46% of every scored LR section. Nearly half your LR score comes from three types.

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.
| Category | Per Section (~27 Qs) | % of Section |
|---|---|---|
| Drawing Inferences | 7.5 | 27.8% |
| Recognizing Elements of the Passage | 4.75 | 17.6% |
| Identifying Main Points and Primary Purposes | 4.25 | 15.7% |
| Applying the Argument to New Contexts | 4.25 | 15.7% |
| Analyzing how the Parts Work | 3.5 | 13.0% |
| Meaning in Context | 1.75 | 6.5% |
| Author Attitude | 1.25 | 4.6% |
Drawing Inferences alone accounts for roughly 28% of every RC section. If you’re struggling with inference questions in RC, that’s where the most points are hiding.

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. We chose not to speculate.
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.
The advantage of staying at the grouped level is that the data is clean, directly verifiable from LSAC’s own reports, and does not depend on any third-party classification system. What you see above is what LSAC measures.
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. Together they answer the question that matters most: where to study next?
FAQs
What is the most common LSAT question type?
In Logical Reasoning, Assumptions, Flaws, and Strengthen or Weaken each appear about 4 times per section (8 per test) and together make up roughly 46% of every scored LR section. In Reading Comprehension, Drawing Inferences is the most common single type, at about 28% of the section.
How many Logical Reasoning questions are on the LSAT?
Each scored LSAT® has two Logical Reasoning sections of roughly 26 questions each, plus one Reading Comprehension section of roughly 27 questions. LR makes up about two-thirds of your scored questions, which is why LR practice deserves proportionally more time.
Which LSAT question types should I study first?
Study the high-frequency types where you also lose points. Assumptions, Flaws, and Strengthen or Weaken dominate LR (about 46% combined); Drawing Inferences dominates RC (about 28%). The right priority is impact = frequency × your personal miss rate, not frequency alone.
What question categories does the LSAT score report use?
LSAC score reports use nine grouped Logical Reasoning categories and seven Reading Comprehension categories. The labels are consistent across PrepTests. They are the categories LSAC uses to tell you where you are strong or weak.
How was this question type frequency data measured?
Directly from 30 PrepTests (PTs 130–159), counting questions in LSAC’s own score-report categories, with no hand-classification of individual questions and no mapping to a third-party prep-company taxonomy.
