I have to agree with practicemore here. Some RCs from PR2004 CD do come back(the one on LDEF, the one on Buccharia capital punishment, the one on political vs judicial theory) but only on 1 of the 4 given tests. I just completed another test and I'm very happy with the score. By the way, the quant section IS more difficult. I had about 5+ combination/probability questions some of which are relatively difficult. Although the level of difficulty may still be slightly easier than the toughest GMAT quant DS number property problems, the overall test does put you in the right mindset and very test like conditions.
What makes verbal harder is that on the 2 tests I have taken so far, they start off with a RC right as of the second question and what happened in the first test I took was that I knew the RC (Buccharia) and memorized my error instead of the right answers. This terribly hurt me since answering wrong questions at first will be more detrimental as the test is adaptive.
Knowing RC passages will actually hurt you more than anything else. Hence, the mere fact that they put RC in the early questions, and RC that you do remember, this will affect your score. I had no such problem with the second test and there was a marked increase.
Just to let everybody know. So far, I'm very satisfied with their CD2005.
