Admission requirements vary according to the law school you're applying to. Typically, law schools look for a well-rounded academic record demonstrating wide and varied fields of study. Another option is to obtain a pre-law degree. Pre-law programs are specially tailored to prepare you for moving on to law school and usually include focus on history, political science and law.
Most law schools require applicants to complete the Law School Admission Test, or LSAT, with a satisfactory score to be considered for admission.
Most Juris Doctor (J.D.) law degree programs can be completed in three years of full-time study. If you want to obtain an LLM (Master of Laws) degree, you'll need to put in another year of full-time study, usually focused on a specific legal specialty.
