AP classes should be available in schools. It allows people to get a better education on said class. People who are ahead of the game need something that will challenge them rather than sitting in a class where they already understand the curriculum.

Personal devices should be allowed in class for certain activities. If you are doing a history assignment and you cant find a certain topic then your phone can pull up thousands of articles on said topic. Or students could record the lecture and review it later for studying in case they missed anything.
