@realteal17, as others have noted, your academics appear quite strong; you are clearly qualified. That’s only one part of the picture. The bigger challenge is differentiating yourself from other applicants, and making a case for why these highly competitive schools should give you a spot over other qualified applicants. You also come from a very tough demographic group (Asian F from California), where the competition is particularly intense.
Your ECs have a couple of interesting points, but you don’t elaborate on them much. 11 years of dancing and 6 of violin should make for a pretty solid music/dance interest. Your “radio show for teens” sounds like it could be distinctive. And you’ve apparently done research at a university - in what area? To what level (publications, etc.)?
Overall your OP doesn’t really do a good job of giving a sense of who you are as a person, which will be critical to succeeding in the admissions process. You need to put together a compelling narrative about who you are as a person: what matters to you, what is your passion, what are you about in the world, what do you want to study/do, how will you take advantage of the incredible resources at these schools, and what makes you different from everyone else who is applying?
RSI is in many ways more challenging than acceptance at top colleges. There are only 50 spots, and really only 1-2 spots for people from California, many of whom have advanced research, participation in top science fairs, etc. By all means apply, but it’s an extreme long shot. You need to show a passion for research, an ability to come up with interesting and productive questions that you would pursue, and make a case for why you are qualified. This will be very good preparation for next fall if nothing else; but you should pursue a range of options (there are many, depending on your precise interest). Since you are interested in SIMR it sounds like your research interest is biomedical; SIMR is quite competitive, but not quite in the RSI class. Are you local to the Bay Area? The SIMR website says that " starting in summer 2016, the selection process will strongly favor local students due to various grant requirements. Non-local students can still apply, but their chances of admission will be much lower."
Other prestigious, funded programs that you should look into include the Simons program at Stoneybrook, the Clark Scholars program at Texas Tech, and the Jackson Lab in Maine. All are highly competitive, and you should have some backup options.
Good luck!
