I have a bachelors degree in Mechanical Engineering from a good university in India. I studied physics in Senior Secondary(10+1,10+2). But I have no individual research experience in physics at bachelors level because in the engineering college we had no choice of major/minor subjects like they get is U.S. or other countries. My knowledge in Physics is equivalent to that of a high school student. I thought of getting admission in M.Sc. Physics but realized that I need a lot of practice to be good at the subjects that form the base of those in the masters course. Can I enroll for a PhD program after my bachelors with no research experience. If no, what should I do to change it?
