Stacey,
I am a native english speak and also a graduate of the Manhattan GMAT 9 week course. My verbal scores hovers around 36-38. I would like to bring that up to a 40 - 42. I find it very very difficult to improve in verbal. One can study SC and even practice CR patterns, but do you recommend practicing reading comp? Is that a useful place to spend time when every passage is different.
Also, I'm considering a Manhattan GMAT tutor to help me improve. I'm pretty decent on quant, scoring approx a 44 in GMATPrep. Is a tutor useful for verbal?
