Well, first, I just realized there is a reason why they wait so long to give grades....until after (at my school) you are 3 weeks into the semester...until you've bought books...they do this all b/c they don't want you to leave!!
Of course, that's lame on their part, and, I think, unfair.
But you should not let one semester of grades--1/12th of your law school experience--make the decision for you. It should be more about you and whether law school is right for you.
At my school, the difference between being in the top quarter and the bottom half was about 4 percentage points. That's it.
What I am trying to say is, you can easily move up. Learn from last semester. Make adjustments. And make personal goals for yourself....try not to think about law school in terms of how you do in relation to others...but remember that ultimately law school is a MEANS to an END. Just focus on the end. there are a million things that matter when being out in the job market other than grades.
And after you get your first job, work there a bit and kick some butt, you can transfer to a better job based on how you did at the first job. then they won't care at all about your first semester grades!!!
