Will I get into a good college?

FYI: I'm American but I'm using the Canadian website because of technical issues.

I'm a sophomore in high school (year 11) and I'm thinking about college. Actually, I've been thinking about college since 7th grade.

I'm at a private school and I get good grades. I had a 3.3 at the end of last semester. I had a 3.8 the semester before, but I had a more aggressive sports schedule (lacrosse and club volleyball) and I got an iPhone, which is very distracting.

Now it's sophomore year. I'm taking Algebra II, English II, common placement US History, Honors Chemistry, and Honors Spanish III. As far as extra-curriculars go, I play volleyball and lacrosse for school and tennis outside of school just for fun. I played club volleyball last year, but it was hard, far, and I didn't like a lot of my teammates and my grades suffered.It'll look good on my application and I'm a much better player so I want to do it again. I'm in my school a Cappella group for the 2nd year in a row and I'm part of BBYO, which is a Jewish youth group. I'm writing an article for the school newspaper and I'm part of the Model UN club. I'm planing on doing community service too (it's actually a requirement) and I want to start a charity.

Yeah, it's a lot.

I want to be a geneticist or oncologist. I have no clue if this is possible, but I want to solve genetic disorders (autism, down syndrome, etc.) in utero, which means in the uterus. I'd also like to find out a cure for cancer in a way that's less aggressive than radiology or chemotherapy.

I want to go to a research school so I can get a good background for graduate school. I'd love to join an a Cappella group, too. I'm thinking about University of Chicago, Berkeley, University of Pennsylvania, University of Michigan, or any good school really. I want to major in Biochemistry so I'm sure any good school will offer a good course for me to take.

What can I do to better myself and get into a good school?

I'm currently at the University of Pennsylvania and I can tell you: it's an amazing place to be. What you have is impressive. And it's worth it that you start taking your GPA very seriously. Not everyone here had perfect scores, but try to stay above 3.7 and work very hard on your SAT. Take challenging classes. Academics count. Make it happen.
