LSAT · Law School Admission Test
The LSAT guide
Learn the current LSAT format, each Logical Reasoning and Reading Comprehension question type, LSAT Argumentative Writing, score reading, and the retake rules before you apply. Each guide is written from LSAC's own public statements, with original practice questions where they help. Start with the format guide if you are new to the test, then move to the question types you miss most often. Read the scoring and retake guides before you register, because the rules limit how many times you can test. Everything here is independent study help, and LSAC is the final authority on dates, fees, and policies. 15 guides in 4 categories.

Choose a starting task below, then use the question-type guides to investigate the errors in your own work.
Choose your next LSAT practice session
Start with evidence from an attempted section. An answer selected after the clock stops tells you something different from an answer selected during the timed attempt. Keep both results. If you can solve the problem without a timer but cannot finish it on time, test a pacing change. If the same answer remains wrong after an untimed review, examine the reasoning before adding more timed sections.
| What happened | Next exercise | What to record |
|---|---|---|
| You chose an answer that repeats the passage but misses the question. | Restate the task before looking at the choices. | The distinction between what the passage says and what the question requests. |
| You changed a correct answer without new evidence. | Write a reason for each change during review. | The exact premise or passage line supporting the replacement. |
| You repeatedly run out of time. | Try a short timed set, then complete the omitted questions untimed. | Time spent, omissions and whether extra time changed accuracy. |
A review note that helps on the next question
Consider an original reasoning exercise: every applicant who submitted a complete file received a receipt; Morgan received a receipt. Concluding that Morgan submitted a complete file reverses the stated relationship. The rule allows other reasons for receiving a receipt. A useful error note is: “I treated a required consequence as proof of the original condition.” Copying the answer letter would not expose that mistake. Test the lesson by inventing an alternative route to a receipt, such as an automatically acknowledged incomplete file.
For passage questions, use the same discipline without forcing every error into a logic label. Identify which sentence supports the selected answer, whose view it expresses, and whether the answer increases the author's certainty. A statement that a proposal might work does not support an answer saying it will work. Keep a separate column for unsupported strength changes and review it alongside your next passage.
Rehearse the actual test tasks
LSAC's format rules describe two scored Logical Reasoning sections, one scored Reading Comprehension section and one unscored section of either kind. Standard sections last 35 minutes, with a ten-minute break between sections two and three. Use your approved timing accommodations when applicable. A short drill isolates a weakness; a complete rehearsal also tests concentration across sections.
Argumentative Writing is a separate task. Standard timing is 15 minutes of preparation plus 35 minutes of essay writing. An approved writing sample, including an eligible prior LSAT Writing sample, is necessary for score release to schools. Reserve a preparation session for constructing a position, addressing a competing perspective and checking that each paragraph supports the thesis. Multiple-choice practice alone does not rehearse that work.
