I think it's safe to say that the examples from the 2005/2008 NBPME questions online are insanely easy than what I experienced on the exam. Most people after studying can get all if not over 95% of the practice questions right. The part 1 I took was very challenging and more medicine than podiatry as probably many people had. I wouldn't develop a false sense of security. Boards in any medical profession are difficult and Part 1 and Part 2 in our field is changing and becoming equally as challenging. So what I recommend is putting in the time and studying hard so you don't have to deal with the stress/money of taking it again.
