I took GMAT again two days ago and got a score of 640 (Q48, V29) again. I had taken my first GMAT on April 11 when I had timing issues in Quant. This time though, I didn't have any such issues. My score first time was 640 (Q42, V36). My GMATPrep and MGMAT scores have consistently been between 690 and 760 in the past month. The first time I took the GMAT, my practice test scores were consistently between 670 and 720. I am really out of ideas on what to do.
I can think of a couple of things:
1. The test is not as standardized as it claims to be and,
2. I am not a very good "actual" test-taker.
