What do I do?I was going to major in bio but I know I wont do well in the math/chem cles.?

I am so there with you. I stuck it out though, and will be finishing my BS in bio in December. You have to know a certain amount of chemistry and math for any science degree. In the great scheme of things, it will probably not matter that you made a low grade in a couple of math and chem courses. (By the way, organic chemistry does not have to anything with math, just a lot of memorization). If med school is your dream, you might not even have to have a bio undergraduate degree to do that, as long as you take pre-med cles. Talk to your counselor. Tell her what you want to do and what you like, and she/ he might be able to put you on the right track.
