Medical Education US

Hi.
I have a BSc in economics (gpa 3.51) and an MaEd. In my country where I got the BSc, you don't take any science classes for a degree in Economics. I am seriously pondering a career change to Medicine. How can I take premed classes. Can I seek out these specific classes in a community college or do I have to enroll in a regular 4 year college and take only these classes?

Thank you.

Community colleges don't offer the level of the science courses that you need to apply to medical school. Assuming you don't want to return to school full time, most people find a university that offers night courses at the proper level for someone to apply to medical school. If you wanted to return to school full time, then yes, you basically are going back to a four year college to take the required courses.
