The reality is that the PE was never hard and will never be hard as long as it is an open book exam.
Many of the hardest exams I ever took were open book. Typically, when a test is closed book the exam material is pared down so that examines have some hope of being prepared for it. In my experience when an exam is open book the same does not hold true. Open book exams have a tendency to ask anything and everything with the rational being that if you have all the resources at your disposal you should be able to find the solution. The problem with this concept is that exams always have a time limit. Given an infinite time table to work the exam I would be inclined to agree that they could be pretty easy, but that is not the case.
As to the original topic, yes it seems to take a long time for the NCEES to grade the exams, I believe they have their reasons for that. I still contend that the only time people really care about how long it takes to get the results is when they are waiting on theirs.
