One of the virtues that can be learned in college is to be happy with what you deserve. Dont be jealous of something that you dont deserve. Also, if you think that four points in a college level class is going to be deciding factor for your acceptance in the program you really want to get in, then you better wake up from the dream now. Your conflict with your instructor might have a more strenuous effect on your future than four points you are having such a hard time giving up on.
