I have a sibling in another medical profession getting ready to take her licensing exam. It came up the other day that each week the exam is given, certain questions are thrown out by an executive committee; therefore, each group has a different percentage considered as passing. She was saying that for some of her classmates, "passing" was 45% or 53% of questions answered correctly! What I'm wondering is if something is similar with the different parts of the NBEO? Is the passing percentage relatively low such as 40-60% of questions answered correctly? That just scared me because I would hate knowing I became an OD after getting (hypothetically) half of the questions right on my boards. Isn't that like undermining the intelligence of the field?! Hopefully this question makes sense to people. Thanks for any input! =)
