The Law School Admission Test, or LSAT, isn't a test of what you know. It's a test of how you think. It measures skills like reading comprehension, logical reasoning, and analytical reasoning—all crucial for success in law school. The exam is designed to be challenging, but its structure is predictable. Understanding this structure is the first step to preparing effectively.

The test consists of five 35-minute multiple-choice sections and a separate writing sample. Four of the five multiple-choice sections contribute to your final score, while one is an unscored experimental section.

Your LSAT score is determined by your performance on four specific sections. These sections can appear in any order, so you won't know which one is which until you're done.

Logical Reasoning (LR): This section appears twice, making up half of your total score. Each LR section presents a series of short arguments, and you'll be asked to analyze, evaluate, and complete them. These questions test your ability to dissect arguments, identify flaws, find assumptions, and draw valid conclusions.

Analytical Reasoning (AR): Often called "Logic Games," this section tests your deductive reasoning skills. You'll be given a set of rules or conditions and asked to determine what could or must be true based on them. It’s about organizing information and making valid inferences from a fixed set of constraints.

Reading Comprehension (RC): This section measures your ability to read and understand complex texts. You'll encounter four dense passages, one of which is a "Comparative Reading" set with two shorter, related passages. Questions focus on identifying the main idea, understanding specific details, and making inferences based on the text.

In addition to the scored sections, the LSAT includes two other important components that do not affect your 120-180 score.

The first is the experimental section. This is an extra, unscored multiple-choice section of Logical Reasoning, Analytical Reasoning, or Reading Comprehension. The Law School Admission Council (LSAC) uses it to test out new questions for future exams. It will look and feel exactly like a real section, and you won't know which one it is. For this reason, you must treat every section as if it counts.

The second unscored component is LSAT Writing. This is a 35-minute essay where you're asked to argue for one of two possible decisions based on a provided set of facts. It's not scored, but a copy is sent to every law school you apply to. You complete it separately online, anytime up to a year after your test date. Law schools use it to get a sense of your writing ability, so it's important to do well.

The LSAT scoring system is straightforward. There is no penalty for guessing, so your raw score is simply the number of questions you answer correctly across the four scored sections. This number typically ranges from about 100 to 101 questions in total.

This raw score is then converted into a scaled score that ranges from 120 to 180. This conversion process, known as equating, adjusts for minor differences in difficulty between different test versions. A score of 150 is roughly average, while scores above 170 are considered highly competitive for top law schools.
