AP Physics questions present a categorization dilemma between K-12 and college levels due to their content, which often aligns with college coursework. Despite using a college textbook, the course is taught in high schools, suggesting a K-12 classification may be more fitting. The discussion highlights that the appropriateness of categorization may vary based on the complexity of individual questions. Ultimately, the consensus leans toward K-12 for better engagement, as there are more active posts in that category. The classification remains a nuanced issue reflecting both educational settings and content rigor.
