In response to the OP, I was thinking about a couple of my first year exams that I asked to review after grades came out. Even having access to the exams, I couldn't tell you how it is that I got the grade that I got. Everything is on a curve, so how on earth can I know how accurate my grade was without actually seeing everyone's exams? Also, there were hardly any notes or comments written on the exams. One of them didn't have a single comment, so I was just reading my own words and a number that was assigned to them by the prof.
Just saying this to illustrate that having access to your exams is not always even remotely helpful in understanding why you got the grade that you got. After my first 5 semesters of law school, I strongly believe that my grades have much less to do with how well I perform than with how well everyone else performs. I've written some exams that I knew were perfectly awful and gotten decent grades, by which I surmise that my classmates' exams were even worse than mine.
(For example, I got a B+ last semester on an exam that I guessed on over half of it because the questions were about obscure things that were barely talked about for a fraction of a single class period, and I didn't bother studying them. Guess no one else did, either!)
Also, for those who aren't familiar with law school grading, I will note that the mandatory curve for first year students at my school is tougher than that for upper level students. I think this is fairly common. In other words, it is much harder to get a higher grade in a 1L class than in a 2L or 3L class, because the overall class average must be significantly lower when the professor turns in grades. If you can't keep up in law school, as someone else mentioned, it's much better to find out your first year than to pay for three years and not be able to get a job at the end. They really do try to weed people out in that first year. Sucks to be one of those people, but it would suck worse to be strung along and not have any chance at paying back the loans at the end.
