I've just registered on this site and will be taking the GMAT in a month. I purchased Kaplan a few weeks ago thinking that all GMAT prep was the same. I took the CAT1 and got a 600, which I now realze isn't too bad after reading a few posts on this board. However, regardless of how I did, everyone seems to think Kaplan CATs are a joke. While this seems to be the consensus on the board, what about the books practice questions or cd practice quizes. Is there any worth in any Kaplan GMAT prep or should I switch while I still have time?
