Is GMAT prep Verbal is different from Manhattan verbal

[Everything OR Nothing]

Dear Stacy,
I have been taking full length tests both from GMAT prep Software and Manhattan.
I have realized that I score fair enough ( 34-38) and I atleast understand the questions from Manhattan.
But some of GMAT prep test questions goes over the the head.No clue at all(always scoring in 24-25)
In my real GMAT also I faced so many questions that do not fit to any rules that I learned from my Mahattan guides or Official guides.

Is it true that real GMAT is totally different than what we are learning from these resources?
I do always correct when i solve questions from OG or Manhattan books (within time contraint ) but in real test I flunk..Many questions go over the head.. why why why.Please help me.I am in dire need of a good GMAT score
