you don't need to be able to type at all. i do type in class and on exams, but next year I think I am going to switch to the old pen and paper. The people who take traditional style notes seem to pay attention better than everyone else. As for the exams, you may want to make sure you dont make a lot of mistakes typing, otherwise people seem to get by just fine writing the exams. Though, for something like torts where you are writing pretty much constantly on the exam, the computer was definitly nice to have. Either way, your typing skills shouldn't make or break your law school career.
