I have been preparing for the GMAT for a while now, however I still have a real low score for the CAT test.

I also do not seem to understand the algebra problems. I have the

manhattan gmat book of algebra, and I have study this however I do not seem to manage.

Additionally, I have done the excersises from the 13th edition and from the quantitative review, I keep making the same mistakes.

According to my log book most of my mistakes are: First- and second degree equations but also the evaluation of expressions.

An excersise like: K- (3-Kˆ2) / (k) = X\K is already really difficult for me.

Do you know perhaps where I can find more of this type of excersises or where I can find an explanation that my help me.

Thank you advanced.
