Hi Tazzo82,
If it's been two months since you've taken any kind of Test (the Official GMAT or a practice CAT), then you should plan to take a NEW, FULL-LENGTH CAT (with the Essay and IR sections) sometime soon so that we can get a sense of your current skills. Once you have that score result, you should report back here (or you can contact me directly).
The Schools that you've named are all highly-competitive and those types of Schools tend to place a greater emphasis on the Quant Scaled Scores of its applicants. As such, while you have a much greater opportunity to pick up points in the Verbal section than in the Quant section, raising your Quant score to a Q49+ would likely also benefit your overall application. By extension, you'll likely have to train to improve in BOTH the Quant and Verbal sections. If you focused your studies exclusively on the Verbal section, then you could conceivably hit your goal score in a month. However, since you've been studying for 8 months (off and on), it's likely that you've developed some 'bad habits' that will take time to fix (and replace with new 'good habits') - so you will likely need another 1-2 months of consistent, guided study to get to that level.
GMAT assassins aren't born, they're made,
