I thought I'd put in my own two cents.
Some of you, believe it or not, will be disappointed and discouraged by your first semester's grades. I've had classmates, some of whom were the talkative types in class, who basically shut up, stopped going to class, etc.
But grades DO change. I was bottom half first semester, and my second semester grades are probably around where the top 10% will be. I mention this because I think people lose sight of the fact that they really can change their fortunes.
I'm not sure that anyone will remember this come january, but I figure it doesn't hurt to try and stem some of the crippling discouragement some people find first semester grades to be. Don't underestimate the emotional aspect of law school.
