How We Decide What to Publish

Every title we publish starts the same way: a working educator tells us where students keep getting stuck on a specific unit, and we ask whether an existing book actually fixes that gap. Most of the time, the honest answer is no — either the explanation is too dense, or the practice questions don't match how the exam actually asks things.

That's the bar for a new title here: not "is there room in the market," but "does this genuinely help a student who's stuck."
