Hi Berk,
First off, both a 700/Q50 and a 690/Q48 are outstanding Scores, so you can comfortably apply to any Business Schools that interest you. As such, an additional retest might not be necessary. Depending on the Schools that you plan to apply to, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/There's no harm in continuing to study, but if you're not going to be able to do so for another 5 months (until we get to July), then you will likely have to work on more than just your Verbal skills. GMAT skills tend to 'fade' over time - so it's possible that you will likely have to work on BOTH your Quant and Verbal skills at that point. Assuming that you choose to continue studying, then your first step in 5 months time should be to take a NEW, FULL-LENGTH CAT, so that we can get a sense of your current ability level at that point.
Before we get to the data in your ESRs, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) For your second attempt, how many hours did you typically study each week?
2) What study materials have you used over the course of ALL of your studies? What 'brands' of practice CATs/mocks have you taken?
3) For your second attempt, 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) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
