Users are seeking previous years' AP Physics C exams for practice, particularly for the Mechanics section, as their midterms will simulate the actual AP exam format. One user, Antiderivative, claims to have all AP C exams and solutions since 1974 and is willing to share them in Microsoft Word and PDF formats. Many participants are requesting specific years' free response questions and solutions, especially from 1995 to 1997, but some express concerns about the ethics of using past exams for study. While some suggest checking College Board for resources, others note that older exams may not be available there. The discussion highlights a strong community desire for access to past exam materials to enhance preparation for upcoming tests.
