Every school is different, of course, but can the Honors class perhaps be as good or better prep for the AP test as the AP class? Our HS offered AP classes that were actually said to be "less challenging" than the honors classes. This allowed more students to have the opportunity to earn AP credit, because it was easier to get into AP versions of classes than honors. I never took the AP class, only the honors version, but that was sufficient to get the desired AP score.
