To achieve 715+, you'll need to improve your Verbal from 74 to 84, assuming that you make no improvement in Q and DI. It's challenging but never impossible.
You need consistent, effective strategy and time management for Verbal. Two articles for your reference as a start:
How to Improve Verbal from V78 to V85Time Management Strategies on GMAT FocusIf you can significantly improve your Verbal, your DI may get a few points lift as well. In the meantime, see if there is any other low-hanging fruit in DI section. You need a 10-point improvement in the sum of your sectional scores, so any thing helps and you need to find the most efficient path to achieve that.
All the best.

Hi Everyone -
I wanted to know if it is possible to have a score improvement of 70 points in a month (R2 deadlines are close). I gave my first attempt and got a 645 (Q88, DI84, V74) and I would like to improve to 715+. I left 1 question in verbal and that seems to have hit my verbal score a lot.
Since my attempt I have been better with verbal and I have changed my approach of solving problems. Im sure that exam anxiety was also an issue and it was not my best attempt. Any guidance would be appreciated.
Thanks in advance
