It’s worth noting that these questions are not necessarily attempting to be AP MCQ clones. Many of them certainly could appear on an AP MCQ exam, and all are linked to relevant LO’s in the new curriculum, but their purpose is to help to illustrate the theory rather than necessarily mimic AP MCQ questions. They still should be of great value.
