Hey, Mona! Yay for pre-med!
I'm a first year med student in Texas, and if you need any advice or such, feel free to talk with me!
I would normally agree with the posts above, but you may want to think twice about the online classes. Some med schools will not accept online class credit or will see it as a "cop out" for taking the real classes at a college/university. You especially want to take ochem and biochem at a university. The preliminary basic science courses you should be able to do at a community college.
Make sure you know your basic sciences, especially physics, because they're all on the MCAT. I actually teach MCAT classes, and I know that the verbal and physics/chem sections are the hardest for people to master. I would suggest taking a prep course for the test because I more than doubled my score using one.
Anyway, hope that helps! PM me if ever you need anything! Best of luck!
