Part 1) I was going through the question of below website. http://www.pmtarget.com/free_sample_pmp_test_questions.aspx and felt that they are too difficult (althoguht they are very good for learning new things) Can any one compare the difficulty level of above site with respect to exam?

Part 2) To make the above question generic.....i found a specific pattern in question ( not only in this site in some other places )
