I looked back a few months but could find no posts that explicitly covered both these so my question to y'all is: From your personal experience, if you had to compose a list of undergraduate math/physics courses that are necessary/extremely beneficial to success in physics graduate school what would they be? Please negate potential PhD topics of study such as the course requirement difference between HEP vs. condensed matter vs. astronomy. A broad, general overview will suffice. To start, the basic consensus for the bare minimum one should have completed I have read on these forums so far is: Math Calculus 1-3 Linear Algebra ODE PDE Physics Introductory Physics 1-3 Intermediate E&M Intermediate Mechanics Intermediate Laboratory Quantum Mechanics Thermal Physics If you had to add to this list, what would you say one should have already taken (i.e. quantum 2, solid-state, complex variables etc.) As I am currently thinking of pursuing graduate school, not only would this benefit me as I consider electives but the many who browse this forum probably thinking the same thing.
