Hey
vivek6199 ,
Here is the thing. As with all of us, verbal is the problem. Looks like you need to change your strategies for RC and CR specifically.
I could see you rushed at the end. Which is the worst thing. If you go through my debrief, I mentioned I got only 25% accuracy(same as yours) in the last section. Reason: I was not able to concentrate because my bladder was about to burst.

Anyways, I would prefer take a little rest and then start working on verbal again. Don't overdo Quant now because you are already good in it.
Go through all the strategies I mentioned and start doing 15SC, 15CR and 3 RC on a daily basis. Make sure you follow POE.
Your aim should not be to get the questions correct but to understand what is wrong with the other options. Drill down all your mistakes and make proper notes.
Practice can make the man perfect but I believe it has to be RIGHT Practice In Right Ways for GMAT.
All the best.
