LSAT Information from a Test-Prep Instructor
First, read. Reading builds the verbal reasoning skills that the LSAT is testing. Read all assigned readings for your classes. In addition, make challenging (but interesting) reading part of your routine—anything that includes a more challenging vocabulary and is written at a higher reading level will work. My best suggestion is to subscribe to The New York Times, The Economist, or a similar periodical. However, fiction is fine, too—I regularly ask my SAT students to read Mary Shelley’s Frankenstein.
Next: Take a course in logic. If there are any advanced courses in logic, take those too. Many LSAT logic games not only test logical reasoning ability, but they also incorporate terminology that is typically taught in logic courses.
Any courses or majors that expand your ability to read and comprehend complex texts, think critically, and analyze arguments will prepare you well for the LSAT. Philosophy, history, English, writing, political science, pre-law... they all offer courses that will help you develop those skills.
