Traced to the source
Every claim about the exam comes from the board's own published blueprint or candidate handbook, cited with the date it was checked. Where a figure that gets repeated everywhere could not be confirmed in a published source, the book says so instead of repeating it. And every title states on its copyright page what its author holds and what they do not, so no reader is left assuming a credential the author does not have. Commissioned authors hold the credential their book covers, and we ask for evidence before a word is drafted.
