GMAT Strategy

I just took my manhattan gmat exam. It is my 3rd exam and just got a horrible 580 (quant 37 and verbal 33). lol I am making some kind of mistake and things are kind of odd in fact humorous. I always thought my math was weak but it was stronger than my verbal. By taking the exam i found that my verbal was weaker. I really thought I had verbal in my pocket. I dont think i have a huge lack of information or know how on the material tested. I think that I am doing something wrong on the actual exam that is more related to strategy. somewhat confused yet very close to my 700.

tommorow I will do a careful analysis of my scores. I am sure this is a normal part of the gradual increase in scores. Can anyone help in some advice?

Manhattan is very difficult. Don't worry about your score. I think powerprep will give you a better picture of your situation. However, keep on practicing with Manhattan. It has helped me a lot, specially in the verbal area.
