OG 10 and purchased the OG11 online
Manhattan SCG (i know somebody who has the SCG +(CR+RC) and he offered to let me xerox it but i like the way the SCG looks so buying a new one

)
Kap800(no CD and last year's version)
Princeton Review(last year)
and a coupla other books which i got fm a friend.
I was told the OG Math and Verbal review isnt really needed as such but that's your call. I've given the CAT thrice and have scored decently each time so those books wouldnt really help me much. I was better off ordering some more tests.
