HI everyone, I will be preparing the GMAT once I receive books from Amazon. (First delivery was stolen from my own apartment.....hopefully the thief will be entering this forum soon

)
straight to the question......
I know that the OG is a must, although it does not contains PERM & COMB problems....In Addition to Kaplan w/CD Rom 2005, is there any other book recommended for students that are not native English-speakers and that really help improving SC, RC, and CR sections?
Thanks a lot for this place, it helps to know you are not alone in the GMAT preparation....
