It depends how bad and how much you have improved. Generally improvement is good thing because it shows you have put a lot of effort in and really tried. If you are looking at the top law schools though, your recent grades will need to be mostly A’s.
It will really depend a lot on your LSAT score and application essays. Enroll in an LSAT course as soon as possible so you can start preparing. Considering your GPA is good but not great, you will want a very high LSAT score, in the high 170s.
