Stuck

I have been studying for the GMAT for the past 5 months and I cannot improve my score past the 660-670 range. I am intimately aware of my weaknesses specifically SC which I spent studying for over a month to the demise of the other sections. I am going to take the test at the end of November or beginning of December. My goal is to get at least a 700. I know with this score and my background and what I want to do with the degree that I would be able to get into the top 5 schools. I have taken the Veritas Prep class, gone through most of the Manhattan gmat books and I have done almost all of the problems specifically problem solving, data sufficiency, sentence correction and critical reasoning in the OG12 and the two supplemental OG's. Closing the 40 point gap is a daunting process and any advice to do so would be great.
