The Law School Admission Test (LSAT) is required for all law school applicants. The LSAT is administered through the Law School Admissions Council (LSAC). Simply log on to LSAC.org to create your free LSAC account and register for the LSAT.
The LSAT is now offered six times each year: January*, March, June, July*, September, and November. The July and January tests are "non-disclosed." This means that you will receive nothing but your score (no test, no answers, no key ...). You typically want to take the test no later than November of the fall before you want to matriculate. Some people wait until January, and some law schools will accept the March test. However, I don't recommend waiting that long.
There are a number of options for studying for the test:
First: UNT offers a course -- UCRS 3000 -- which includes LSAT preparation as a key component. The course is a graded course offered in the fall and intended for students in their Junior year. Please contact the pre-law advisor for further information about material costs and the process of admission.
Beyond the walls of UNT:
LSAC has recently partnered with Khan Academy to create a free online prep program.
Some people prefer to study with books such as the Kim LSAT Trainer or the PowerScore Bibles
Some prefer commercial online programs like 7Sage
There are also in-person programs like Kaplan and Princeton Review.
Your choice should depend on how best you study and your price point.
Whichever method you choose, you should supplement your study with practicing actual tests. You can purchace books of ten actual tests from Amazon; the books are under $25. The Pre-Law Advising Office hosts a number of practice tests every semester. Watch the newsletter for information about where and when.
