I found this pertinent analysis of the differences between GRE and GMAT on the PowerScore official website:

In the end, it's up to you whether you feel more attracted to maths or learning words by heart...

Anyway, don't be upset! If I can take a stab at it, I'd say you haven't used a lot of high quality material out there. You could really boost your prep by studying from the guides recommended by most people around here or by using their strategies.

All thes best no matter what you decide!

Try one more time with more preparation and you will be fine.

Thank you guys for the support.
Would you recommend me buy Kaplan math book? I noticed in the forum that Kaplan books are good for those who aim 500-650. Is that true? Which one would you suggest me?

Yeah some guy keep posting this post. Probably he is employed by the veritas or even more likely by Manhattan GMAT. I study GMAT on and off, all of my books havent arrived yet so I cant really comment. However I did use Princeton Review extensivly and McGraw hill. I have glanced over Kaplan but did not really study it as it is so similar to the material I was using. I think Kaplan, PR, are good books, but very limited. Their practice exams are good, however, not extremely accurate. So to sum up, I think Kaplan is good, but it certainly has its limitations. Most people use MGMAT as I found out to increase their score after Kaplan. Also I heard Power Score books are fantastic for verbal (although you dont seem to have much problem with it). So in my opinion, you have to find out your weaknesses and address them, whether it will be with a GMAT study guide like Kaplan, or alternative sources unrelated to GMAT but related to a topic you are trying to master...
