Hey.. happens man. The same thing happened to me. Just be regular with the Verbal section. Do it everyday. Dont focus on how much you can finish in a day, instead focus on how much you understand, and why do you not undestand, what you dont. Remember, the key is to understand and remember what you have studied. The verbal section can make or break your score.
I got 660 the second time around, primarily because of better performance on the verbal section. Go through the link below.
