So I have taken the past 3 months off. My wife and I decided to move and we are building a new home now... Taking advantage of some really reduced real estate prices and the fact that the cost to build a home is now back to 2004-2005 levels....
My question, what should I do to get back into this? I had been scoring in the upper 400's to upper 500's, as sad as that sounds, before I took a break.
I have the following:
OG11 (3 copies for some reason

)
Manhattan SC
OG Quant
Kaplan 800
GMAT Club exams
I used Princeton Review's online course (the one where you go at your own pace), and I thought it was "okay." That has since expired.
Suggestions?
I want (need) to score in the upper 600's.
Thanks.
