I was going to be a biomedical engineer at first. I was also going to go to Boston University as a biomedical engineering student. And, I was going to be premed as well.
Boston University is pretty expensive though. In high school look at biology classes and especially chemistry classes. Remember, most of the people who drop out of med school don't drop out because of biology being too hard, but usually because of the chemistry involved, especially organic chemistry. Well, that's all I can offer.
