Hi samco.me,
In another post, you mentioned that you had already scored a 660/Q49 - and that is a strong Score, so it could be enough to get you into your first-choice School. As such, another retest might not be necessary. There's no harm in continuing to study though - and you could potentially pick up a bunch of points in the Verbal section. Based on your ESRs, there are a number of similarities in your 3 performances - and it's likely that you've gotten "stuck" in a certain way of thinking about the Verbal section that is keeping you from scoring higher.
I understand why you might be looking for a 1-week 'crash course' in the Verbal section, but you will likely need closer to a month of consistent, guided study to get to the point that you can consistently score at that higher level. You've likely developed some 'bad habits' during your prior studies that will take time to fix (and replace with new 'good habits'). Thankfully, the GMAT is the same consistent, predictable Exam that it's always been, so you CAN train to score at a higher level.
Before I can offer you the specific advice that you're looking for, I have a few questions about your prior studies and your goals:
1) Over the last 3 months, how many hours did you typically study each week?
2) What study materials have you used during that time?
3) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
4) What are the exact application deadlines that you are facing?
GMAT assassins aren't born, they're made,
