Well, I hope it all works out for you! My sister is doing acting, she starts in September @ Guild Hall :3
I'm planning on going to either Princeton in America or University of Kent, both are 4 year courses and you get a Masters in Astrophysics if you complete them. My Dad said that although America is really expensive, it would be very good job-wise and with Kent you'd get a year abroad in America to study but have a while to think about it so should be alright in the end.
