I'll be honest. You use more your head than your mate. That will be payed at the end. We used to have those, and even with the cheat sheets. I never used them. Some teachers even dared to ask me why I wasn't using them. I told them: That's cheating and it doesn't make my brain work. That payed off...a lot!
Those teachers are to be those horrible ones when they say to bring your chet sheets and books.
