The LSAT takes roughly half a day to complete. Scores range from 120-180; the mean score is roughly a 151. It has six components. There are 4 scored sections of multiple choice questions on every LSAT. Each of these sections lasts thirty-five minutes.
Logical Reasoning (two sections): In these sections, arguments are presented in short reading passages. The questions are designed to determine whether you can understand the argument's point, follow the chain of reasoning, recognize weaknesses in the argument, or draw inferences from the given evidence and premises.
Reading Comprehension: This section presents you with four samples of scholar-quality compositions. Six or seven questions then correspond to each sample. These questions test your ability to do things like understand the reading passage, define a word based on its context, infer ideas not explicitly stated in the reading, or recognize the structure and organization of the reading.
Analytical Reasoning: This section offers four or five logic puzzles and corresponding questions. These puzzles usually present a series of statements and requirements regarding several people, places, or things who share certain relationships and/or preferences. The questions require you to make inferences from the information provided.
In addition, there are two unscored sections on every LSAT.
Experimental Section: There is an unscored thirty-five-minute multiple choice section on every LSAT that is used to field test new questions for future exams. This section will look exactly like a Logical Reasoning, Reading Comprehension, or Analytic Reasoning section, and you will not know which section will be scored and which will not.
Writing Sample: The thirty-minute writing sample, used to measure your ability to efficiently arrange and clearly express your ideas and argument, is also unscored (and bears considerably less weight on your chances of acceptance at law school), but it is sent to each law school to which you apply.
