When should I take the LSAT?
You should take the LSAT one time (if at all possible) when you are the most prepared to take it. It is offered only four times per year: February, June, September/October (depending on the year), and December. Law schools will see all of your scores so do not take the test before preparing! Most law schools take your highest score but some consider all of them. You can only take the LSAT three times in any two-year period.
If you plan to go law school the fall following college graduation, you will need an LSAT score by September/October (depending on the year) of your senior year at the latest. If you can be ready for the test in June between your junior and senior years, it will give you a month after classes end to focus solely on LSAT preparation.
