Every ABA accredited law school accepts the LSAT and more and more accept the GRE. A strong LSAT score is valuable to law schools because that is what they report to USNews and other ranking programs. If you are planning to only take the GRE, then you can mark the next couple steps as complete becasue they are LSAT specific.

A diagnostic LSAT is the best place to start. Your score on the diagnostic is not very important. What really matters is how comfortable you feel with each section so that you can decide if you want to use a prep course, a 1-on-1 tutor, or study on your own. You can find a free diagnositic on Khan academy. This is also a good time to make an account on LSAC.org because you will be using that site a lot. Making an account is free but there are fees you will have to pay too LSAC to do much else.

This is the first point where you can actually plan out the next weeks/months/years. In the whole process, you have the least control over the LSAT dates, so they are good thing to use to plan everything else.

Not everyone is eligible for an LSAC fee waiver, but this is an important step. If the ~$1500 dollars it costs to apply to law school is going to be a financial burden then we recommend applying for a fee waiver. You might not get it, but it can't hurt to try. The LSAC will not issue any refunds if you are approved for a waiver after you pay for something, so apply for a waiver early.

Everyone's schedule will be slightly different based on how you are going to prepare (self, course, or tutor) but the important thing is making a plan

You can register for the LSAT about a year out and the deadline is typically one month in advance of the test.
