LSAT (Law School Admission Test)

LSAT

Logical Reasoning, Reading Comprehension and Argumentative Writing, with original questions throughout.

AI-drafted · awaiting expert reviewThe LSAT as LSAC gives it from August 2024 through June 2027: four 35-minute multiple-choice sections (one scored Reading Comprehension, two scored Logical Reasoning, one unscored variable section) and the separately taken, unscored LSAT Argumentative Writing, described for the 2026–2027 testing year, in which most test takers sit the multiple-choice test at a Prometric test center. LSAC has announced a three-section format with embedded unscored questions from the August 2027 test; the first lesson describes it. Facts verified on lsac.org on 9 November 2026.

A complete, original course for the LSAT as it is given today. Logical Reasoning is taught family by family, following the skills LSAC lists: the parts of an argument and its method, the formal logic of conditions and quantifiers, assumptions, strengthening and weakening, flaws, inferences, explanations, points of disagreement, principles, and parallel reasoning and analogy. Reading Comprehension covers structure and main point, details and inferences, the author's attitude, application and new information, and comparative passage pairs. Argumentative Writing gets its own unit, with original prompts in LSAC's described format, a rubric in our own words and model essays. Every lesson has worked examples, common traps and a Check yourself list, and every practice question has a full explanation of why the right answer is right and why each tempting wrong answer is wrong. A full-length practice test mirrors the three scored sections and their timing, with an Argumentative Writing task. Use it alongside LSAC's free official PrepTests on LawHub.
