If you ace that precalculus honors final (i.e. get what would be considered worthy of an A grade) easily, then taking precalculus will be a waste of time for you. In this case, go straight to calculus.
If you do not ace it, then you may want to take the course to cover the stuff that you did not learn as well while self-studying it.
If you do take a post-AP math course, will it be a dual enrollment course with college credit?
