GMAT for a 3rd Time?!?!

I just took the GMAT for the second time. My first attempt I got a 670 (42Q/40V). I studied for about 6 weeks and took it again and got 700 (44Q/41V).

I am happy with the overall score, but a bit concerned about the Q split. I don't have the desired 80%.

I have a civil engineering degree, but only a 3.0 GPA (For certain reasons, and my GPA trends upwards in my last 2 years). I also have a very non-traditional application profile in major project construction and consulting. (I'm a white, American male, 27yrs old)

I am debating taking the GMAT for a third time before the end of August. I typically score 46+ (with some 48s) in Quant on my CATs, and just think I had a poor test day on the 2nd GMAT.

I have the following questions:

- Given my low GPA, do you recommend I take the GMAT again? (Assume that I will have very good applications, essays, and recommendations)
- If I were to score lower on the 3rd GMAT, would I absolutely kill my chances?
- Would I be better off focusing on applications and getting everything in for Round 1?
- Would taking the GMAT again by end of August put me in a serious time crunch?

I'm shooting for top 15 schools. (A few top 7)

Thanks so much. Look forward to hearing back.Image may be NSFW.
