Meh. Whatever. Then I might as well take Advanced and then AP of both physics and chem since I'm going to see it again later and I'll probably remember it better too.
I use math as my study hall. I have so much time while waiting for everybody to get the concepts.
It will only slightly aid you. Most people in college taking chem and physics would have taken it last about 2-3 months before starting class as mainly seniors take it. Yeah, you won't entirely forget it but it won't be in the for front of your memory
