I make average/above average grades. My overall high school GPA is about a 3.3.
High school and college are generally very different. People who were at the top in high school may find themselves in the middle (or even at the bottom) in college; people who were in the middle or at the bottom in high school may find themselves closer to the top. If you go far from home then you'll be experiencing a major lifestyle change and a lot of personal development. Combined with the fact that your high school probably taught you quite differently from the college (and may or may not have sufficiently prepared you for college studying), nothing is a given.
I made the mistake of assuming that because I had an easy time in high school, that things would be the same for me in college. That cost me a few semesters in terms of grades. Go in there expecting it to be difficult and to struggle, and you'll probably do very well. Never become complacent.
Like many other people, I thought having a science major would better my chances in getting medical school, but after reading several threads on the subject, I've learned otherwise. I've decided to major in Business Administration. Now I need to know how exactly my classes will work. What year of college would I start my pre-med classes? Would my pre-med courses ever interfere with my business major classes, I mean would I ever have to end up taking summer school because of course overload?
You're very smart - it's true, medical schools generally don't care what you majored in, they just care about your grades (and the grades from one major aren't weighted in relation to another - a 4.0 from the easiest major possible is better than a 3.7 from the hardest major possible). In recent years there's arguably been a backlash against traditional science-trained applicants, but it's hard to say whether there's real discrimination or whether it's just that people got smart and started taking easier classes (read: not science) and getting into medical school that way.
It's a total perversion of what I think the education system is supposed to be about, but here's a tip for you: shuffle your schedule to be as advantageous to you as possible, and find and take the easy courses. Every school has those types, I think; at my undergrad institution you could tell which professors were easy because a ton of the sports players would be in those classes. Those are easy A's. I despise that advice, however, because I think that college should be about taking courses that really interest you and/or that would expose you to things that you might not otherwise have had exposure to. Thinking about it this way makes college nothing more than a game of grades, and strategy around it. Don't go overboard with that advice, but keep it in mind, and know that some of your competitors vying for slots in medical school will be doing that.
As to when to take the courses, whenever you can fit it in. At my institution we had a minor for pre-meds who weren't taking the standard science major. The minor consisted of the pre-medical requirements. Your adviser (whether business or not) should be able to help you figure out when to take which courses at what time.
And would any of you reccomend me going to a 6-year medical program in Antigua right out of high school [my mom really wants me to do this].
Absolutely not. As a general rule. US medical schools (whether allopathic or osteopathic) are much more preferable. Once you finish medical school you need to get into a residency program. That's when you're officially working (and you get paid, but not much), yet you're technically still in training. Graduates from the Caribbean schools have a harder time getting into a residency program; foreign medical school graduates also have a very hard time getting into residencies. It doesn't mean you can't be a doctor or that you'd be a bad doctor, but it does make things difficult on yourself.
For example, I know of a guy who did one of those six-year programs straight out of high school, in a European country. Sure, he has a MD, but it's been years and he still hasn't been able to secure a residency position.
I've wanted to be a doctor my entire life, nothing else feels right for me.
Just out of curiosity, why do you want to be a doctor, and how do you know you'd be unhappy doing anything else? If you know what you want to do it's quite admirable and you arguably have a leg up on people who were unsure of what they wanted to do. But at such an early stage in life, and with arguably limited exposure to other working fields, how can you really rule everything else out? Don't drop your goal of medicine, but definitely stay open to the things you'll experience in college.
It's a long, hard path to get into medical school, and it doesn't get any easier from there on. It's good that you're focused this early, but take care that you don't burn out.
