I wouldn't worry, I have a friend that took hers and she knew for sure she failed. She also got 75 questions and the last question was a question over a disease she had never even heard of and she knew she got it wrong, but the computer shut off right after that question. Long story short she passed. just remember the computer isn't just grading you on your last question, you could have already proved yourself "safe" before it even got to that question. I just took my Boards yesterday and also got 75. I'm still waiting for my results. What in the heck takes them so long to post the results. The longer I wait the more I think I failed. AHHHHHHH!
