Final Verbal Push - Hitting 45-47

Hi guys,

I'm taking the GMAT next Saturday. I've taken 5 practice exams over the course of last two months and my verbal has been consistently 41-42; 3 Practice exams from Economist GMAT Tutor and 2 from GMAT Prep.

Initially, I had problems with CR and RC when taking the Economist tests. Then I started practicing with Powerscore CR bible, and my accuracy rate has consistently improved with each exam with regards to CR and RC. In the last exam I took (GMAT Prep), out of the 8 errors, 6 were SC and 2 were CR.

Out of the 6 SC:
2 were silly errors - Didn't see the missing participle.
4 were always down to choices that seemed really similar and I chose the wrong one.

One thing I've noticed is that I'm always finishing verbal with ~15-20 minutes remaining each time. I've tried slowing down, but it seems to be really difficult for me. I seem to be really confident of my choice during the exam.

I've downloaded the Brutal SC package, and the 100 tough SC questions from GMATClub to work on it.

Is there anything else I should be doing? Any tips, suggestions would be welcome.

Cheers!
