When you take the LSAT depends on when you’ll be applying to law school. As a general rule, you’ll want to take it no later than the January administration. For example, if you plan on attending law school in September, you’ll want to take the LSAT no later than January of the same year so your application is on time for most schools’ deadlines. Depending on your schedule and when you’ll have time to study, you may want to test over the summer in June or July of the year before your intended start of law school.
