Hi Syavashp,
If you took your first Official GMAT in 2017, then you took the prior, longer version of the Exam. That 680 (with a V41) shows that you had (and appear to currently still have) strong overall critical-thinking skills - which is great! Depending on which Schools/Programs you plan to apply to though, your overall applications would likely benefit more from improving your Quant Scaled Score than by picking up those additional points in the Verbal section.
The scoring algorithm on the Official GMAT is far more complicated than most people realize. Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT scores can vary a bit based on the 'biases' involved in their respective designs. The most realistic CATs available are the 6 from GMAC (the 2 free CATs, and each of the 2 that come with Exam Pack 1 and Exam Pack 2), but retaking a CAT that you've already taken is NOT a realistic way to assess your skills - since you will likely see some 'repeat' questions that you have already faced. Unfortunately, seeing even a couple of repeats can 'throw off' the Scoring Algorithm and impact your pacing, energy levels, fatigue, etc. (meaning that they would likely all appear to be better than they actually are). In addition, taking CATs/mocks in a way that does not properly match-up with how you take the Official GMAT can cause similar effects to your score restuls. Thankfully, the CATs from Kaplan and
MGMAT are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion).
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying recently and your goals:
Studies:
1) Over the last 9 weeks, how many hours did you typically study each week?
2) Have you used any other study materials besides the course that you mentioned? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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)?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) 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,
