The Part I of the board was a very hard exam this year. I thought it was definitely harder than the OITEs and also different. The question stems are alot longer and there is plenty of Qs with alot more choices than just A-E. Lots of MRIs, CTs, videos of physical exam, and questions with sequential answers that you can't go back once you answer them. The failure rate for this year exam was ~21% and ~18% last year. The failure rate has always been around 10% up until 2 years ago when the exam was changed to a computer format (then the rate doubled). I wonder if the computer format of the exam makes it harder to pass. The percent Qs right you have to get to pass each year is about 70% of all questions.
