lazgirl, why are you starting out with such a defeatist attitude? On this thread and the other one you started about the easiest schools to get into, you sound like you could really use a confidence boost.
Yes, it's hard to do the work involved in getting into medical school. But people do it every year. There ARE people getting the As in freshman chem - they're not necessarily the brightest people in the class but they're certainly the hardest workers. It really can be done but you have to be determined, and you will have to work hard even if you are usually a "lazgirl."
If you're really not sure you'll be able to hack the pre-med track when you start college, I'd suggest that you go a little easy on yourself in your first semester. You don't HAVE to start out with the pre-med classes; another approach would be to get acclimated to college with other coursework, get used to the independent work habits you have to practice, and then get into the tougher courses.
But please start thinking positive, okay?
