How the books are made
Exam prep is a market where the incumbent books are often old, padded, and written by nobody in particular. These four rules are how we intend to be worth buying instead.
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.
Exam blueprints change, usually on a published cycle. Every title states its edition date and the blueprint version it covers, on the cover and on the copyright page. When a board republishes, the title is reviewed and either updated or pulled. A stale exam guide is worse than no guide.
A guide is not a textbook. We follow the exam board's published domain list and its weightings, so the chapter that carries 28% of the marks gets the space that share deserves. What the exam does not test does not go in.
We never promise a pass, a score or a pass rate, because no publisher can honestly promise any of them. We tell you what is on the test, how it is scored, and where candidates lose points. That is the whole offer, and it is enough.

No. Credential Press is independent. Exam names and trademarks belong to their owners, and every title says so. We cite the boards' own published material and link to it, which is the only honest way to write about an exam you do not administer.
No, and we will not. We tell you what the board says is on the test, how it is scored, and where candidates lose points.
A named author on the cover instead of a house byline, a printed edition date instead of an implied evergreen one, and a scope that follows the published blueprint instead of the subject at large. Whether that is worth your money is a fair question to hold us to.
