some law schools look at the lsat the most, some look at gpa the most and the better the reputation of the school, the better one's chances...shoot for at least a 3.0 gpa and a 150 on the lsat, 160 greatly broadens your chances, and 170 is almost a ticket to ride (with a good gpa though)
the average lsat class (kaplan for instance) generally ups one's lsat score 15 points...going in cold to the lsat is not good...my cold lsat score was a 144, a full 6 points below the aba school average...prep class should put be into the high 150s which would be good enough for me since i am not, at my age in my 40s, shooting for stanford and leaving me in a situation where i may not live long enough to pay off all the loans, with interest
the lsat does not measure intelligence or aptitude and the only way to get a good score is to practice it over and over...the local law school where i live had a phd take the test and score a dismal 120 on the lsat...the test is hard and unlike any test out there...so prepare for the lsat in the context of the lsat and not the sat, gmat, or iq test
if you have the time and independence, be willing to go to the best school you get accepted to, no matter where you have to move to and no matter what it will cost...if you are young, you will have a lot of years to make money and pay off the student loans
if you can't move and you are busy with work and/or family, then study online or part time (4 years instead of 3 in that case) if your state bar association allows you to and get the best law school you can find in that context
the best law schools are both aba accredited and regionally accredited and if you think you might move to another state in your working life, then only be concerned with an aba accredited school so you can take the bar in all 50 states, pr, and dc
and to cover all bases, if you think you have to move out of the usa, to the uk or canada *or one of many british commonwealths for instance, then get a dual jd/llb degree like i am considering
i hope this helps
