Help with upping my GPA and getting scholarships. ?

I'm going to be a Sophomore in high school this coming school year. And I realized that even if in the next three years I achieve a 4.0 GPA then I will only be at a 3.2 GPA. I was wondering what Scholarships I could get with a 3.2. I want to go through Pre-Med and then take my MCAT, and go on the road to being an Orthopedic Surgeon. But I'm afraid that I won't have a high enough GPA to get scholarships to pay for Med/Pre-Med school. I realize that with a ridiculously low GPA this past school year you may suspect I am unable to do work on that level. But that is not the case. I scored in the top 1% on the national benchmark tests or whatever they're called. (the ones where you take a bunch of tests and they give you a percentile, like what percent of the students at your level are ahead of you.) and have scored Advanced in every state standardized test I have ever taken. All my councilors say I'm a genius and that I should be doing better in classes. And I know they're right. But I'm not really a genius in the sense that I let it all go to waste. I was just wondering if you could tell me ways that I can get my GPA up and If I couldn't any good scholarships I could apply for that would take a 3.2.
