Yea, at my law school, 90% of students use laptops for exams. And generally (I think) mult. choice questions rarely make up more than a third of any exam (that may be different for fourth tier schools, as they focus more on preparing students for the bar exam, which has a lot of mult choice). And many exams (most exams at many schools) have no mult choice or short answer questions at all -- only issue spotters.
