@kissthegmat:
Thank you. I did not do all the 8
Manhattan books. I read the SC book and the CR book. OG 12 can be completed within 5 days. PS and DS does not take too long. But, still I could not complete all the DS questions in the book. I spent most of my time on verbal. RC was pretty straightforward. My accuracy in SC was 85%, CR 90% and RC 85%.
The 650 that I got the day before.... well I was interrupted 4 times during the course of the test! Someone kept ringing the doorbell!

(I gave my GMATprep 2 from 2pm to 6pm).
Best of luck everyone!
Cheers!
