Your academics are outstanding. I see you want to major in math. Should you really be looking for a tennis scholarship? It means 3 to 4 hours tennis a day, and travel to tournaments, and being at the beck and call of the coach. Not to put down (the few
) high-achieving athletes, but these athletic scholarships usually go together with a "dilute" major, like English or Business. Ouch will get killed for saying that but that is OK. Math is a different beast, specially if you combine it with a minor in physics, engg or applied sciences. And graduating with a C average in your major does not look good if it is math - paints you as sort of a stupid but egoistic fellow. While a C in English would paint you as a rebel who is too creative for the establishment.
I think you should consider applying for an academic scholarship, and then play tennis for fun.
If you want to know the nuts and bolts of a tennis scholarship, search for posts by "megacedu" and a thread called "megacedu goes to college" or something like that. She stopped posting, but before that used to write her life down - how to get a scholarship, what happens after that, blah blah blah.
