Also my verbal score is stuck between 37-40 and I want to push it beyond at least 42. Before I ask my question, Few points I would like to put forward:
A) In all practice sessions, My scoring rate is around 90% in SC. In MGMAT, in every mock I just got one or two SCs wrong per mock. However, on GMAT prep, the numbers of incorrect questions increase to 6 or 7. I don't know why.
B) My CR is a weak point but I do manage it and same is with RC.

In all mocks my minimum verbal score is 38 and maximum is 41. But as I said, I'm Determined to get above 42. My GMAT is scheduled for 4th August, 2017.

So my question is:
Is this improvement possible in one week?
What should I do to improve my score?

Reply soon as I have my GMAT within a week
