Cambridge university or Oxford. I probably won't have any chance at getting there, but I would like to apply once I'm done highschool. Right now I'm at a 95% average, and I'm taking academic courses instead of applied. I've heard of stuff such as GCSEs and A*'s and I have no clue of what they are. I live in Canada right now, and I would be so delighted to have someone assist me. What my GPA would need to be to what courses I would like to take. I'm very interested in astrophysics, physics, astronomy. Most of all I love cosmology and math. Do you guys have any idea? Would I need to be reconized as a foreign student or what? I'm getting really stressed right now. By the way, my GPA is around 3.74. Edit: Also, I graduate my highschool at 17 years old, and I've also heard that mostly everyone is older then 18. Would it be smart to enroll in a foreign exchange program and get my GCSE's somehow that way?
