My friend is currently doing her prerequisites and hasn't taken the sciences yet. She wanted to know if it was ok to take AP 2 before AP 1, or take AP 1 first. I myself have taken them, and know the difference, anatomy then physiology. But couldn't answer that one for her because I didn't take it in the order she wants to take. Basically she wants to know, for people who have done the second first, if it was easier since she isn't that great in science. Whats any advantages of taking AP 2 before AP 1, and how would taking 2 first apply to taking 1 after she is done. Also she will be taking this online. Hope anyone can answer that for her, Thanks :)
