Well I don't know what pre-AP is, but I was in all honors courses from 1st grade on through. There were years when I had teachers who were just awful, and like you daughter, I would stick it out. I always ended up getting great education from the class, but the road there was tough. I would say for her to go ahead and sign up for the pre-AP math next year and see how it goes. Would she be able to switch out mid-semester? I had to do that with an English class my sr. year of high school because of an odd teacher no one could please.
BTW... Good for you for being so involved! My parents were never really involved in our school work; they just complained if our chores and homework weren't both done, though some days there just wasn't time for both.
