What courses can I take in college to become a doctor?

Answer 1

When you are in college, you will have to talk to your pre-med advisor for specifics, because some med schools have different requirements for their applicants than others, but basically, you'll have to take:

2 years of chemistry, with labs, including organic
1 or 2 years of biology
1 year of physics
1 semester of calculus
1 year of English
1 year of a social science (i.e. psychology)

Answer 2

You need to have a strong science background, bio in particular. You need to do well in school and do well on your mcats. That will get you into an MD program then you can become a DR.
