Logical Reasoning

LSAT question types.

Logical Reasoning is roughly two-thirds of your LSAT score, and it rewards classification: each question type has a fixed task, recognizable stem language, and its own trap patterns. Learn the type and you know what the right answer has to do before you read a single choice.

The guides below cover the eight core types. Each one includes the stem language that identifies the type, a step-by-step strategy, a fully worked original example question with a complete answer breakdown, the trap patterns wrong answers rely on, and answers to the questions students actually ask. Work through them in any order, though if you're starting from scratch, main point → flaw → assumption is the sequence that builds each skill on the previous one.

Frequently asked questions

How many LSAT Logical Reasoning question types are there?

Most systems classify 12, 15 distinct LR tasks. Eight families do the heavy lifting: flaw, assumption (necessary and sufficient), strengthen, weaken, inference, main point, parallel reasoning, and principle questions.

Which LSAT question types are most common?

Flaw questions typically lead the count, followed by the assumption family, strengthen/weaken, and inference questions. Together those types make up well over half of a typical scored LR section.

Should I study question types separately or do mixed sections?

Both, in that order. Type-focused drilling builds the recognition and tactics; mixed timed sections then train selection and pacing. Skipping straight to mixed sections is the most common self-study mistake.

Do these skills transfer to Reading Comprehension?

Directly. RC questions are largely main point and inference tasks scoped to a passage, and the same evidence-standard applies: supported by the text, not merely consistent with it.

Not sure which types are costing you points?
