LSAT Logical Reasoning Study Guide — 160+ High-Yield Concepts

162 high-yield concepts for the modern LSAT's LR sections

The modern LSAT (August 2024 and later) is a Logical Reasoning test — two scored LR sections of 25 questions and 35 minutes each are 50 of the 75 scored questions, two-thirds of your score. This focused workbook teaches 162 high-yield concepts across 9 parts, each with key facts, an LR tip, and an original example: the modern format decoded, argument anatomy, formal logic (conditionals, sufficient vs necessary, quantifiers), the full question-type taxonomy (main point, must be true, strengthen, weaken, assumption, flaw, parallel, principle, paradox, evaluate), a 26-flaw catalog, and a tested strategy system (pre-phrasing, eliminate 4 / defend 1, flag-and-return) plus a test-day blueprint. Independent study aid — not an official LSAC publication; pair it with LSAC's official PrepTests for the strongest results.
