How does one decide? The kid tells you over and over that his high school honors classes are too easy. So if the only option that is harder is AP. He is still just a kid with a life after school. So how do you balance the busy work of AP...what is the magic number of AP classes? 9th grade he took one and got a five on his test. This year 10th he is taking 2. I anticipate he will take two or three next year and it is possible to take 4 or 5 12th grade. But is that what he should do?
