Thats good. I hope you really like math. I went to Ohio State for astrophysics, but I couldn't handle the math load. The physics wasn't that bad, but when I looked at my classes I needed 5 math classes beyond calculus, and 12 physics classes, not to mention the astronomy classes. I would of liked the astronomy classes the most, but the physics and math killed it for me. I didnt like working out 20 problems for 4 hours a day per class. I was one of 48 astronomy / astrophysics majors out of the 58,000 students that went there. Not a high demand field. I also lost interest in it because of chameleons. I rediscovered my love for reptiles once I adopted my cham, and now im going for zoology, and I like it so much better. When I was 9 I used to say I wanted to be a herpetologist, and now I might get the chance to work with reptiles later on. So im happy. What aspects of astrophysics are you getting into? Are you going to be more observational, or say mechanical and build the devices?
