Sorry to sound like one of those people, but it's spelled calculus, I am fairly sure.
I think I had a bit of a misunderstanding. If these were bonus questions claimable by only one student, I think that's just setting yourself up for a bad time, and is a bit of a stupid policy. I thought these were questions that he was exclusively asking each person on a test or the like. In this case, I believe that it's a stupid policy, but because of it's stupidity, this isn't a bad thing to do within the confines of said policy.
I just happen to be good at math personally, so I get good grades without a lot of work. I would be heartbroken if I was flunked just because I got everything right, but didn't work enough. As I stated, to me a college course may not be there to teach you something, it may just be there to give you the credit and prerequisite that you need and couldn't get otherwise.
