absinthe

I think this is the place for my question. I'm a student of English (in my 2nd year currently). I've got some plans about studying medicine, too. So, is there a possibility of enrolling to a US medical school once I've got my BA? After all, I will have four years of studies. On the other hand, they will be asking for some courses in Chemistry and Biology. Could I possibly take some tests to prove my knowledge in those fields since I won't be able to take Chemistry/Biology courses at my faculty?
