The LSAT tests critical thinking and analysis skills through three scored sections, an experimental section and a writing sample. The reading comprehension, logical reasoning and analytical reasoning sections each contain 22 to 28 questions with a time limit of 35 minutes each. It is not expected that you can answer every question in every section. Familiarizing yourself with the test instructions and question types will allow you to answer as many questions as possible.
The best way to study for the LSAT is to take practice tests. These will allow you to familiarize yourself with the test and assess your strengths and weaknesses. You should always take practice tests in test conditions under actual time constraints. It is best to obtain previously-used tests from the Law School Admissions Council (LSAC), which offers limited free tests and also sells books of practice tests.
LSAT study books can help with one specific section or the entire test. If you have a lot of time beforehand, use a book that focuses on the entire test, with practice questions and tips for each section. For many students, the analytical reasoning section --- better known as logic games --- is the most challenging. It is also the easiest to study for and there are numerous workbooks dedicated to the subject.
If you have the time, LSAT prep courses can be a very valuable way to study for the LSAT. The courses available will depend on your area, but PowerScore, TestMasters, Blueprint, Kaplan and Princeton Review all offer LSAT prep courses. All offer practice tests, study materials and the assistance of a trained professional. Classroom and online courses are both available and often a score increase is guaranteed if you have previously taken the test.
