Stalla PassMaster is brutally hard!

I was doing some exams where I got some really good results. But who has done the Stalla Passmaster software? I find some of the questions brutal. Am I the only one or does anyone agree?

I found some of the questions difficult, but attribute it to the lack of my ability to recall the concepts. Have you done the end of chapter (EOC) questions yet? I’d like to hear a comparison between the two.

Yes, I have done the end of book questions. I just found that some of the questions were rather tricky and seemed to be rather contradictory to what was taught in the books. I am now printing them out and reviewing the really tough ones in the hopes of determining where I am having trouble.
