I have been recently accepted into a graduate school for nuclear physics. After reading the departmental website, I believe my first-year classes will consist of core courses such as classical mechanics, E&M, and quantum. I will have a lot of free time during the upcoming summer, so I want to put those time to good use. My question is: is there a list of books that I should go through during the summer to give myself somewhat of a headstart? Is there something I should be doing besides reading ahead?
