LSAT | Logical Reasoning

LSAT Prep | Logical Reasoning


The logical reasoning section of the LSAT took its present form in 1991.


The logical reasoning section typically comprises about 50 questions out of the approximately 100 questions that go into a test-taker's LSAT score. This section is therefore the most important section on the LSAT, serving as the basis for essentially 50 percent of one's final LSAT score. Reading comprehension (about 28% of one's LSAT score) and analytical reasoning (often called "logic games," at about 22% of one's LSAT score) are second and third in importance, respectively.


Each modern (i.e., post-1991) LSAT comprises two scored logical reasoning sections. Each logical reasoning section contains approximately twenty-five (25) short passages, most commonly one paragraph in length each. Each passage is then followed by a question to be answered or a statement to be finished.

The question or statement is then followed by five possible responses, lettered A through E. Only one response of the five possible responses is the "credited response," i.e., the right answer.


Each logical reasoning section is allotted 35 minutes.

Technical Information

Unlike the GRE or GMAT, the LSAT is a paper-based test. A test taker's answers must be recorded ("bubbled in") on an answer sheet using a soft lead pencil, which answer sheet is then scanned and electronically graded. No credit (or penalty) is given for marks in the test booklet. There is no penalty for guessing.

Strategy and Tactics

Many LSAT preparation companies are available today to assist students in preparing for the LSAT and the logical reasoning section thereof. LSAT prep companies typically provide in-class instruction regarding logical principles, test-taking strategy, and diagramming techniques. These LSAT prep courses may also include proctored mock LSATs. LSAT prep providers may also offer online LSAT training, computerized analysis of a student's LSAT performance, and one-on-one LSAT tutoring.
