What are my chances?

<p>I am a 13 year old freshman at a high school in Virginia. I am really worried about getting into colleges when my time comes. I have a 4.27 GPA & I have always been an A & A+ student. So it will remain this way. In addition, I do a lot of volunteering. This includes volunteering at libraries, hospitals, etc. I also take rigorous courses during the years. For example, I am a freshman & I am taking honors Biology (a sophomore class) & Alg. 2 with Trig. (a sophomore/junior class). The only thing I really lack are extracurricular activities. I am no good at sports. What kind of extracurriculars should someone like me do? Any suggestions? Also, what other suggestions can you guys give me to make sure I will get into some college. I am really worried. My parents keep me worried all day & night long; they think what I have is not enough. Part of me agrees, but is it really all that true? Please help!!!</p>

<p>P.S. My goal is to get into UVA, which works out because I have the in-state advantage.</p>
