Need expert advise Please!! I need good material!!!!

[marlboro]

I've got the exam in two weeks!!!

Goal:700

I started studying for the Gmat two months ago and I scored a 610(Q47 V28) in my first Gmatprep.
Then I bought the Kaplan book with cd 2009 (quite obsolete I know) and I realized that those test scored very low (540 in
my first and last kaplan test).

I decided to change the material study and I bought the pack of six manhattan test. My first score was 580 (Q44 VB 28).
I found the quantitative part more difficult than the ones that I have tried before but I did not worry.
However, today I have started doing a new manhattan test and I've found the quant part tests another kind of maths.Manhattan problem makers love integer properties too much....I guess.


Does anyone can explain what do I have to do? Forget about companie's tests and keep studying from the official guide
and its littles sons (verbal an quant review) and try the second test of gmat prep?

HELP ME PLEASE!

I agree the Manhattan Gmat is a different kind of maths, they are more difficult, but most importantly after knowing how to do these difficult questions doesn't help the GMAT. I used the Official Guide to prepare for my first Gmat attempt and I scored OK, and then I used Manhattan Gmat for my 3rd attempt and my quants score was a mediocre! I don't know what other materials are good though as I'm also figuring out myself...
