Hi, I finished my junior with a C+ in physics and a B- in math. I am looking to get into an engineering or astrophysics program due to the fact that i have been obsessed with the universe ever since i was 7. Any advice on what to due this summer to try to compensate for this? I am currently watching the classic mechanics Mit course and reading Calculus for dummies. I also am planning on taking the Physics subject test in the fall. Thanks!
