<p>Hi, I don't know if this is the proper forum for my question but... </p>
<p>Okay, so I really want to get to nationals for USNCO next year (I will be a sophomore next year). Last year, I took both biology and chemistry as a freshman, which is quite unusual. My school only allows 5 classes (it's a competitive prep school) so I can't double up on the sciences again as a sophomore if I plan to graduate high school:P Anyways, my options are: take AP Chemistry as a sophomore and take Accelerated Physics (introductory physics course, but it prepares you for AP physics B) as a junior or take physics next year and then take AP Chem as a junior. Normally, kids take bio, chem, physics and then take an ap course, but I'm considering switching the order. I have no previous experience with Physics whatsoever except a bit in middle school, but I doubt it'll be that helpful. Does AP chem require any knowledge of physics?</p>
<p>I guess I'm also scared to take AP Chem because I'm afraid my grade won't be as high...:/ I'm also afraid to ask my adviser because I'm afraid he might get mad at me. (he's a nice person, but he might get annoyed that i'm asking to switch classes... idk:// what if i switch to ap chem but find it too hard for myself and end up asking him to switch me back to physics???) </p>
<p>Also, to do well on the USNCO (I know my chances are really low, but I want to make it into the top 20 really badly!) will it help a lot to have taken ap chem already? I've ordered the Atkins textbook and I'm willing to study hard on my own:) </p>
<p>Sorry for the bit of rambling, and thanks so much! Anyone with experience with USNCO will be appreciated! :D</p>
