UPenn, Berkeley, and Stanford

You may check previous threads iI have posted for grades, ECs, or anything else. I am 25% Native American (red skin which is a very small minority out of all NAs). How could this help me?

from last post
I am a sophomore at a Jesuit High School in LA and have been playing tennis since I was 9. I am playing aggressive tennis and playing at tournaments. My rank has improved and I would love to play at Stanford for their team. I am Native American and am 25%. I have not registered since my grandmother is sensitive about talking about her past due to the fact that her father left the family to rejoin the tribe. I am very interested in learning more about my culture. I was the ASB president in middle school and received the presidents award for gold level hours in community service. I took a trip to Nicaragua and held a school drive for supplies (while I was president). I went to the school there and played with the kids. I am planning on doing another trip to the dominican republic. Sophomore grades are 3.7 for 1st semester and 3.9 for expected 2nd semester.
