Hello,
Thank you all for your help in the past few months.
BUT I really need some serious help / advice / methods to drastically improve my score!

I took the gmat last saturday and completed bombed it...
I am quite surprised at how poorly I did.
470 20Q 30V

Maybe someone can help me explain it, and/or help me to study in a more effective manner in my study efforts before I retake next month.

I've always been pretty good at math, I think maybe I just overthought too many of the easy questions and didn't check my work.

I thought I was going to nail it when the first question popped up, but after I did the calculations my answer wasn't one of the choices so my confidence went down the tubes. Then I was rushed after spending too much time on these easy ones. Stubbornly retrying to get the right answer because I knew that I knew how to do them.

I went through the OG book, took both prep test 2 times each and was scoring in the high 500 - 600 range.

My initial thoughts are too download the mgmat tests, and order the quantitative study book. But I really think it was just a stubborness / confidence issue.

Are there any materials out there to help pinpoint what areas you need help in?

thank you!
