Taking 100 CATs won´t make you score higher

I decided to buy Manhattan´s CATs after my Kaplan in'person class expired and I hadn´t reached my goal score. I got a 640 and was aiming for 700+

I took all the CATs and carefully reviewed all of them, question by question noticing where I made avoidable mistakes, but still after taking all 6 CATs my score did not improve. In total I´ve taken Kaplan´s 9 CATs twice, the free tests from GMAC, some from the economist to enter their contests, and the 6 from Manhattan... my conclusion, taking lots of CATs won´t make your score increase magically.

Overall, Manhattan´s CATs are, have challenging questions and great explanations.

But I need more than that to increase my score,so just purchased The Economists complete plan... GMAT Club will give you 10% discount on it so take advantage if you want to buy it. Hopefully this time I reach my goal score and finally get done with the GMAT!
