Hi renguard,
Looking at your scores (V23 Q42), it seems that you lacking the core skills needed to ace the GMAT (both in verbal and quant).
I feel that even through you have gone through the books, you haven’t been able to learn and assimilate the concepts and their application properly. I would say going through the books again doesn’t seem a very good idea at this stage. I am saying this because if that way of learning were to work for you, you would have grasped the concepts and their application well in the first go itself and it would have reflected in your mocks.
Books can teach you the concepts but do a very poor job of teaching you the application. I would like you to view some of the files from the links below
