Doing well in all my class so far

It has been about a month and here is how I am doing:
Calculus 3 - Don't have exact assigned grade, but I have gotten 100% on all but 3/9 quizzes and he drops the lowest 3. Also, we just had our first exam last Thursday and I am pretty sure I did very well on it.
AP Environmental Science - 96.8%, easily one of the most interesting, applicable classes I have taken
AP US History - 96.4%, still missing an assignment though, but I kick butt at this class

Physics - 100.5%, and I am missing six assignments, haha. This class is a joke, but it is regular physics, I guess. It's required at my school before taking AP Physics.
