Hi,
First I would work on catching up with my verbal score a little. To try and get it to the same ballpark as Quant. Work on some grammar basics, as this will improve all areas of verbal. From here, I would look into a good adaptive course to take. Doing so will help you determine your weak areas in each subject. After determining your weak areas, focus on those and do not move on until you have completely mastered them. If you progress too fast, your lack of basic concepts will hinder your ability to perform on the more difficult questions.
Are you currently using a prep course? If so, which one? If you do not feel prepared enough, do not hesitate to postpone your exam a month to put in some extra time, but that is only if you feel necessary. If you have any other questions please feel free to ask.
Sincerely,
Evan
