Will this get me into harvard....what chance do I have ???!?

Dang, I'd say yes by far compared to my stats. I'm not up to par with prestigious colleges, small universities I prefer, but I would contact the department head of a certain major you are wanting to achieve at Harvard, and introduce yourself and try to get signed up with the school that way instead of going through admissions. I always call the program coordinator instead of directly talking with admissions even at community college and ask questions because than they will see how dedicated you are. Good luck, and you have a lot of extra curriculer activites and show that you are dedicated to helping your community. If you are convincing and determined you can get anywhere. Oh, and btw, you need to watch "How High" about two stoned rappers, Method Man and Red Man, who got into Harvard. If they can you can lol.
