Hi KushalDhiman,
If those practice CAT scores are accurate, then you have to make some serious adjustments to how you deal with the Verbal section - and all of that work is going to take time. As such, you should consider rescheduling your Test Date. While I understand that this might not make you *happy*, it's highly unlikely that you're going to hit your goal score in 2 weeks time.
1) How long have you been studying?
2) What resources have you been using?
