I graduated 6 years ago with a low GPA of 3.2 (BEng from UK).
Have recently scored a 100% in GRE math and 96% in verbal.
I have 5 years work ex , with a few impressive research assignments under my belt.
I want to apply for PhD from a good (top 15) universities. My question is - is it really worth spending on application given my low GPA? thanks a lot.
