I would be in college in 2019 (currently I'm in standard 11). I'm greatly interested in Quantum mechanics, QFT, QCD and Quantum Geometerodynamics. Of these, I want to do an internship on the first, because I don't think I'll be able to touch the others till the 2nd year in college. I'm living in Kolkata, and I intend to do an internship in India. Nevertheless, prerequisites should be same across good universities in the world. I want to keep myself prepared to the greatest level possible so that I can apply for internship as soon as my summer holidays start. What are the basic necessities that I must have in order to do an internship in QM? The topic may be anything on QM. What should be the minimum level of knowledge that I should have before I can apply for an internship? I'm seeing many of my seniors suffer while doing internships because they were not aware of the prerequisites, and they are taking much longer than usual to finish the internship. I don't want that happening to me. Hence I want to be prepared as far as possible.
