I go to calss baked a lot. Sometimes it's a bad idea but I usually just handle it and a wait for the end of calss and go home. I have a calculus calss in college three days a week and I go to that class stoned almost every day. I took an exam about two weeks ago stoned of a few bowls of chrondo and got like a 89%. When I know the material, smoking helps. When I don't, I shouldn't smoke.
