Harder than the Real Thing

I took the Manhattan GMAT CATs as part of my prep through Manhattan GMAT. I had heard from a lot of people that it was harder than the real tests, which I found to be true for the math section. The verbal section does a pretty good job approximating what the real test is like, probably better than any non-GMAC test.

In my opinion, the biggest difference between these tests and the GMAC ones is that here the difficulty trends in a linear fashion (question correct --> harder next question), whereas the real tests will drop down in difficulty a little bit when introducing a new concept. If you get most of the early questions on these tests right it becomes brutal pretty quickly, which I found not to be the case on GMAC practice tests or the real test.
