Some states do the right thing and reveal scores.
Although it is an NCEES policy for NCEES to not do so. But NCEES has to give the state boards the grades. And some state boards give out the grades. If you fail, you can take your diagnostic report, along with your grade, and calculate exactly the number of right/wrong answers you got for each category of questions.
One engineerboards.com member erroneously said, "People with 52, 53, 54, 55, and 56 ALL got the same 69." Well, ... He is wrong!
I would like to poll all members who have failed the PE, received their grade, and compared it to the diagnostic, to "Reply" to this post with your own experience.
