Hello friends I hve done B.Tech in electronics engineering from ISM dhanbad, a premier engineering institute in India. And I have a very core interest in physics from very early but i couldn't choose physics after my school due to some reason. Now, I am finally decided to pursue physics ahead and I am starting to prepare GRE physics. Need help about " how to start"... "from where to start" ? And I also want to know whether it will be possible to switch or not ... how tough it is? How much score in GRE physics should I need to get admission in a good university in US or Europe ? What extra should I do to increase my chances ? And kindle suggest some books for GRE preparation ? ( for classical mechanics, relativity, E&M Statistical Physics, Atom & Nuclear physics and for experimental part also) Please help !!!
