Hope you are well. Great job on your Quant! 10 days isn't a very a long time so if possible I'd say give yourself a bit more time. But assuming that you have to take the test in ten days let's see if we can identify some places for quick improvement.
What seems to be the issue in verbal? What's your greatest verbal strength? What's your greatest verbal weakness? Is timing an issue? As you are taking a practice test are finding that the verbal section is challenging or are you surprised by the scores? What materials have you used in your GMAT studies so far?
Let me know the answers to these questions and anything else that might help diagnose the issue and we'll try to get to the bottom of this.
Have a good day,
"It is a curious property of research activity that after the problem has been solved the solution seems obvious. This is true not only for those who have not previously been acquainted with the problem, but also for those who have worked over it for years." -Dr. Edwin Land
