Hi aimtoteach,
I'd like to know a bit more about the last CAT that you took. You'll have to do a question-by-question review of everything (even the questions that you got correct).
1) How many questions in the Quant section COULD you have gotten correct but didn't (due to a silly/little mistake)?
2) Did you have to rush to finish the Quant section (and if so, how many questions did you have to guess on to finish on time)?
3) In the Verbal section, how many questions did you 'narrow it down to 2 and "guess" on?" (whether you got them correct or incorrect).
That last question likely defines the 'root' of your problems in the Verbal section. It doesn't sound like you're approaching the Verbal section with a tactical approach - I think you're just trying to "figure it out on the fly" and you're choosing answers that "sound good" instead of answers that you know are correct. At your current scoring level, the GMAT becomes really 'sensitive' to little mistakes, so to score 700+ you can't afford to be making too many of them.
GMAT assassins aren't born, they're made,
