LSAT Logical Reasoning

The LSAT contains two logical reasoning sections of 24-26 questions each, commonly known as "arguments" or "LR." Each question begins with a stimulus that presents either an argument or a short set of facts. The stimulus paragraph is followed by a question stem that asks the test taker to perform one of 22 cognitive tasks.

Below, we have organized these tasks in the relative order you should master them, essentially our free logical reasoning book guide. However, the Zen LSAT analyzer's algorithm is built to make sure you practice on the tasks that will most efficiently improve your score to your potential, so it is a far better guide to build your self-prep. Each task page has an introduction for how to complete the task, and a questions tab where you can find practice materials and explanations.
