Gmat Practice Test

I got a low math score on a GMAT practice test. Where can I get help with the Math portion?

It’s a great idea to take a prep course–when I started studying for the GMAT, I noticed that I hadn’t seen many of the concepts since high school (if at all), and I needed some structure and focus. I went with Powerscore on the suggestion of a friend, and found it very helpful. The instructor was great (they all score in the top 1%), and the approaches I learned were very effective. By the time I took the GMAT, I was comfortable with the concepts, and very confident. For whatever it’s worth, I ended up scoring a 770.
