So get a step ahead and study the chapter from the book that they may not teach. People in online college courses do that all the time, and I mean learn from the book. If you can't do that I don't think you should be in an AP honors class. The teacher is there to help make learning the material easier, but you should be able to study and learn it on your own.
Of course if you run into a problem ask your teacher and they should be able to answer any question... otherwise they should not be teachers!
