Well, how to get into Harvard Law… Applying for a law school is often a lengthy process with lots of preparation to be done beforehand, at least two years prior on average. While most law schools have their own requirements for applications and deadlines, visit their website to know their system well.
In general you will need to: prepare for LSAT which serves to be your main entry to law school, research the law schools in detail, make a LSAC account and register for LSAT, once you finish the test, have the official transcript sent to your LSAC, along with academic scores (high GPA is the easiest way to make you more attractive as an applicant) and any other letter of recommendations. Then schedule and prepare for the personal interviews. Then make an essay that stands you out and you are ready to go! You might get rejected on the first try, but many people do too, keep trying or go for other options.
