Thank You for your encouraging comments , but I am a bit nervous ,i gave my first attempt in Jan and had prepared a lot for that ,then took my second in April and messed that up ,so I am not very confidant right now about where my preparation stands , also another attempt would mean preparing rigorously for at least another month or 2 to get it up all the way to 750 level , and that means the deadlines will be very close and proper application time will be lost , so keeping in mind these 2 factors i think i would go ahead with my application with this score itself, what are my chances with may be if not the top 10 but the the next 15 ie from 11-25 schools , i am not sure though , please advise.
Warm regards,
Sidd
