He's trying to learn it.  He said he had a horrible instructor, so he came here for help (which was a mistake on his part).  But you all get off on the fact that you've passed Calc 2, and you want to ensure that as few people as possible attain (and surpass) your mediocrity. That way you can continue lording it over them.
