Hi friends ,
I am an electrical engineering student , interested in applying M.S in physics program in Europe . So i have started preparing for this , when i searched the web how to study for PGRE , most effective and common suggestion is go through the recommended books( recommended by Yoni kahn in their website ) for each subject and solve the problems in it . When i did for classical dynamics of systems and particles by marion for the second chapter , the problems are conceptually easy but mathematically rigorous which means it take 10-15 steps to get to the answer , whether this kind of problems will appear in the PGRE exam or not ? and whether i have to read all chapters in these books.
