LR = Law Review? For a 1L in first semester?
To get de-bumped in a class, you will typically have to @#!* up several times, be disruptive in class etc. Missing a question when called on never gets you debumped, at least I have never ever heard of that happening.
It's not different, there are people who like to talk for the sake of talking all over. There's good active and there is retarded active, no disagreement there. But you get more out of your education if you participate, that's pretty obvious.
