The Four Types of LSAT Sections
The LSAT includes three types of multiple-choice sections — Logical Reasoning, Analytical Reasoning, Reading Comprehension and — and a Writing Sample section. (See Overall Structure of the LSAT.) Here's a brief description of each component (the links take you to more details about each one):
An LSAT Logical Reasoning section provides questions that gauge your ability to understand, criticize, and draw reasonable conclusions from brief (one- or two-paragraph) arguments. All questions are multiple choice.
An LSAT Analytical Reasoning section provides questions that gauge your ability to understand a system of relationships and to draw appropriate conclusions about those relationships. These questions are presented in four groups, 5-8 questions per group. All questions in a group are based on the same premises and series of conditions. LSAT Analytical Reasoning sets are often referred to as logic games. All questions are multiple choice.
An LSAT Reading Comprehension section provides questions that gauge your ability to read carefully and accurately, to determine the relationships among the various parts of a passage, and to draw reasonable inferences from the material in the passage. The questions are presented in four groups, each group pertaining to the same passage of text. All questions are multiple choice.
The LSAT Writing Sample exercise gauges your ability to formulate a reasoned, persuasive argument; your ability to compose an organized, coherent essay; and your facility with the English language and the conventions of standard written English. You'll be given a prompt that presents two alternatives and asks you to write an essay in which you argue for one alternative over the other.
