Top Law Schools

I am about to graduate this fall with a mechanical engineering degree this fall with around a 3.5 GPA from Penn State. My lsat score is a 169.

I plan on applying to all of the best law schools but I'm not sure about my GPA. All the profiles I've seen were 3.9's and 3.8's that got accepted to harvard and yale etc. But their majors were english and literature and philosophy and the likes.

Did anyone get accepted to these law schools with a lower engineering GPA?

a 3.5 GPA is a 3.5 GPA. Combined with a 169, it's highly unlikely you'll even get waitlisted anywhere in the T6.
Retake.

Short answer: no. Law schools look primarily and overwhelmingly to the hard GPA score - in part for ranking purposes.

Edit: Looking at MyLSN.info, it looks like you need to get your LSAT up to 174 in order to have a shot at the T6. Even then, history says that you're SOL for HYS.
