need some advice

[ability]

Hi
Thanks everyone for sharing your gmat experience.
I have noticed that everyone says that gmat maths was not as they had expeted it to be.
I am doing alright in Official Guide maths, is the maths in real gmat really difficult to handle if you rely only on Official Guide. I got a 640 score in PP1 before touching Official Guide. I felt i could do better if I work hard for sometime.
But it seems things are very unexpected in Gmat. The PP results no longer seem indicative of your real score.
Please guide me as to what other books should i use to prepare myself for the more difficult problems.
I am writing my gmat in mid october so there is hardly one month left.
please advise...
thanks

Try Kaplan 800...they've got some pretty hard math questions.

Yes, Kaplan is crazy like that, but they do prepare you well for the actual test. It's like running a marathon with all 26 miles going uphill. That's Kaplan. Then when you actually go compete in the real marathon, you realize that it's only half-half, so it seems much easier.
