<p>where can i find practice bio/physics/chem olympiad practice tests online? i'm planning on taking all of them this year, but i'm only takin AP BIo and AP PHysics so i'll prbably have to self-study chem.
i've tried googling but cant find any. maybe i'm just googling it wrong........
i know there are some out there. or maybe they're for sale, like the AMC problems. how do u suggest i prepare for them, like what textbooks should i use?
for bio i have the AP Campbell edition (i heard it's no different from the college campbell edition, is that right?)
for physics i have the halliday book
wht is the best book for chem?
thanks!!</p>

<p>i kno it seems silly to be taking all of them when im not really good at any subject right now -_-. but i want to so help please :)</p>
