I have done my B.E Mechanical from Mumbai University with aggregate of 61% and diploma in Mechanical Engineering (MSBTE) aggregate 60%. I want to pursue MS in Energy systems in fall 2014. I have gap of 3 years(I failed in the 1st and 2nd year of diploma). So can you please suggest what GRE score should I aim for to get into a good uni? I have taken a mock test and got a score of 302 (155Q: 147V). I am taking the GRE on 20th Jan.
