In order to qualify to take the LSAT test you must be pursuing, or have completed an undergraduate degree from a recognized institution. You can take the LSAT test regardless of your Grade Point Average or the course you are pursuing, but typically law schools require a GPA of above 3.25 and favor double degree students during the admissions process. If your GPA is considerably lower then you will need a very high LSAT score to compensate.
The LSAT test can be taken four times a year. The majority of law schools require that you take the LSAT in the December session in order to enter law school the following fall. However, most students take the test in the June or January sitting, to give them time to retake the test if they receive a low score. Some students even take the test in the first year of their Bachelor's degree, although this is not required.
The LSAT test is designed to test your potential to excel in a law career. In order to gain a good test score you need to have the relevant skills and approach. The test consists of five 35-minute sections including multiple choice questions on reading comprehension, analytical reasoning and logical reasoning. Together these measure your ability to understand complex material, draw logical conclusions and to analyze and evaluate information. The test includes a 35-minute writing sample which is taken at the end of the test. This is not marked, but it is sent to all the law schools you apply to and is used as part of the admissions criteria. It is best to take a series of practice tests before entering for the real thing.
You can repeat the test if you do not feel your test score is reflective of your true ability. However, a full record of your test scores must be submitted as part of your law school applications. You cannot take your LSAT more than three times in a two-year period.
