I will be applying as well!
This seems like the perfect program for me, as there aren't any opportunities in my area (that I've found) for advanced astrophysics, which is a field that really interests me.
I have really strong skills in math, but due to limitations at my school I haven't had much experience with physics and astronomy. Last year, I was the only sophomore ever to take AP Calc BC at my school, and am now taking Calculus III and Differential Equations at a local community college. I also just joined a math circle at UC Davis. However, my school requires us to take regular physics before we can take AP Physics B, so I'm stuck in that right now. It's quite frustrating, really, since I already know all the material. On the bright side, I will be taking AP Physics B in the spring, so I won't be too uninformed.
As for astronomy, it is actually one of my favorite fields of study along with molecular biology, but I haven't been able to find ANYTHING in my area for it

I am considering signing up for an astronomy class at my local community college for next term, but with differential equations plus a varsity sport and coaching a team I don't see how I will be able to fit it into my schedule.
I know SAT scores aren't a make it or break it deal according to the previous posters, but does it help at all if one scores well? I took the November SAT and am anticipating a score in the 2300-2390 range (find out this Tuesday!).
One of the reasons I really want to participate in this program is to help decide what career I want to pursue. Up until recently, I've been sure I wanted to be a doctor, but I don't know if all the education and money for education will be worth it in the end. Aerospace engineering and maybe other engineering fields have started to become more appealing to me.
Oh, and I don't know much at all about computer programming. Or computers for that matter, lol. Should I make an effort to catch up on the subject or does it even matter?
Anyway, sorry for the babbling, but good luck to all those applying and thanks to those who have provided information about their experiences!
