In a nutshell, my prep was the following:
1) I took a course with Princeton Review. 1st GMAT Try: 570 Q: 41 V: 27
2) PR Cracking the GMAT: 2nd GMAT Try: 660 Q: 41 V: 40
3) Manhattan GMAT Self guided study course 3rd GMAT Try: 660 Q: 38 V: 42
The last practice test I took I got a 720 (Q 48 V 40) I used the GMAT PREP tests.
I believe I can do better. Im not sure about the real ROI of retaking or even if it would hurt my applications.
Wow! You went from 27 to 42 in Verbal... How did you do that? Most people would kill for such an improvementl. So my guess is you focused more on your verbal and maybe ignored quant. Then if you could raise your quant to 45 you'd be in good shape.
In quant you went from 48 on GMAT Prep to 38 on the real thing. This could mean you either focused on super hard quant questions and not enough on the intermediate level ones or you got nervous during the exam.
I may be wrong but from what you say this is what i think.
1) You are clearly able to make dramtic improvements in your scores (see verbal 27--> 42

). If you can go from 570 to 660 (increase of 90 points) you should be able to go from 660 to 750 (increase of 90).
2) You may have paid less attention to quant generally or too much attention to difficult problems at the expense of perfecting your fundamentals (my mistake)
3) You get nervous during exams.
If your quant problem is coz you focused on only hard problems then I would suggest refocusing on fundamentals not on the super hard questions and try bring your quant score to the 46+ range
consistently (meaning on 4 or 5 different tests you get 46+ in quant). If you can do this, then a retake might be worth it.
As a general matter, I would suggest retaking only if you are consistently scoring around 750 in your practice tests so that even if you lose 50 points to nerves you are still at 700.
But then you'd have to also consider even if you were to get a 700 how much would that help your case... given it's the fourth take and you got two 660s. To answer this you should ask one of the consultants on this forum. If you got 760, I think most places wouldn't hold the two 660s against you... but 700?... I couldn't say...
But as VP_Jim says, it's probably better to perfect the rest of your app. 660 is good enough for most schools.
