I am currently studying mechanical engineering(M.E.) in India. I want to pursue physics as my major in US or Canada. I need to know what are the requirements for that if i want to be accepted in a good school for masters and what extra for physics should i do side by side with my current M.E. course? What is the university going to want to see in me since i am not doing bachelors in physics? I don't have any physics course in my university.
