Hey! I will start my third year on the theoretical physics program. I have taken an introduction course in particle physics, just the basics, not much math. (quark and Feynman diagrams the forces and interaction , CRM matrix and cabibbo angle etc. ) Now I'm choosing between relativistic electromagnetism (which seems like a great course) and particle physics. I want to do general relativity, quantum gravity and string theory in my master. I really think that particle physics is extremely boring, I simply don't click with the standardmodell and the formalism, its nothing for me. But I know that quantum gravity models is a lot of particle physics on higher energies. So am I stupid not to get good at particle physics and take the advanced course? Or can I be sloppy about, course-wise, until I need it? Can someone give me some advice here based on their experience? Thanks in advance!
