i have done mechanical engineering from India. i gave the general gre and score 327 (167 and 160), but I did very poorly in my graduation( 5.31 pointers with 13 backlogs) I then worked for 2 years in a mechanical engineering firm and now have a sound knowledge of mechanical engineering. i gave the subject test preparing on my own and scored 770( i want to know if its good or not). now i want to pursue my masters. should i go for a masters program in mechanical and then look for phd in physics or another ms program or any other course ? or what course should i go for now ?
