Same here...I thought my questions were getting easier and easier but at the end I ended up with a good score..so don't worry..sometimes its hard to assess the difficulty...some questions that appear easy to some might appear difficult to some others and vice versa...

I had the same thing happen to me. I couldn't really tell if the questions were "harder", but some of them were more in depth and or took longer to get to the answer but I wouldn't say they were hard.  I just think it had to do with the fact that I completely over-prepared so I felt I should have known the answer to most, if not all of the MC questions.

Not sensing them get harder may be a good thing. Might just mean you were familiar with a lot of the material that was tested and that you are in good shape.
