Suggestions for the AP Physics 1 course

The exercises and videos in the AP Physics are helpful in understanding basic concepts, but I do not feel they in any way adequately prepare students for AP Physics 1 level questions. I would like the question and videos to tackle more complex AP-type questions. The questions are way too easy and are not at all comparable to AP questions. I like to use Khan Academy to review for course tests and AP tests, but this for this specific course it was not helpful.
