I am trying to apply for PhD program (finance or accounting) in United States. I am looking for tier 2 universities; however most of the Tier 2 Schools demand minimum GMAT score of 600. I have already given GMAT twice and interestingly my GMAT scores increased by 100 points when i gave it second time. I don't want to give GMAT again because if my score doesn't improve, I will just look dumb. Right now my score is 580. Shoul I focus more on letter of recommendations, Sop and other stuffs or give GMAT again?
My undergraduate GpA is 3.8 and my MAster's gpa is 3.91
Please help me
