Hi ymba2020,
Since you're so close to your Official Test Date, you should NOT be doing too much studying (at this point, you don't have enough time to make any major changes to how you handle the Verbal section - and trying to 'cram' would likely hurt more than help). In these last couple of days, you should limit your studies to general practice and light review (NO CATs and NO 'cramming') - you would be better served by getting some extra rest so that you can go into Test Day calm, clear-headed and ready to work.
You might find it helpful to review the Verbal questions that you 'narrowed down to 2 choices, but got wrong' on your last couple of CATs. If you were that close to selecting the correct answer, then you just missed some detail/aspect of the prompt right at the end - so there might be some patterns in terms of details that you consistently miss (and thus, cost you those points). Again though, you should NOT be putting in lots of study hours at this point.
GMAT assassins aren't born, they're made,
