You probably need to change your strategy drastically.
I think a big thing in Verbal, and even Quant , is to understand the patterns in the questions, and looking for things that are consistent and you can only do that with lots of practice and attention.
Try to understand what the GMAT is trying to test you on, and how they will try and trick you, and act against it. I think that is a big advantage for us. Sometimes by the makers always trying to trick you, it goes to our advantage. Since you can eliminate extremely "obvious" answers
The problem is how fast can you spot the trick in the question??
By your quant score it looks like you need to understand more basic level stuff. GMAT Math Bible is a good start for you.
Also pick up the
Manhattan GMAT books, all of them. If you study with them you can easily raise you score 150-200 points probably within a month. Then you go from there.
