I am going to start highschool and would like to get a PhD in Astrophysics, but I feel that I'm behind. I am barely going to take algebra 1 in my freshman year. I am going take summer courses so I can get caught up. Now all I would like to know is what is expected to go to CalTech and any good physics books to read so I can know a lot more of physics compared to everyone else. In my 8th grade year, they taught me Laws of Motion, I would like to know more about that and many more physics concepts. I really enjoy physic, my passions are science, computers, and Dota 2.
