Law School Discussion

Hi everyone, I'm new here and just had a question.  What's the minimum GPA acceptable for most law schools if you have a high lsat score.  My first year marks were pretty bad mainly due to personal reasons, but since then they've went up significantly each year.  Do any law schools take top 3 years or anything like that?  or would it be possible to retake a  year?  Do they consider that some schools mark harder than others?

Any input would be appreciated thanks.
