Yes, University of Maine accepts AP credits. Refer to the college's website for their specific policy on AP credits. A college’s AP credit policy will lay out the minimum score to earn credit for a given exam, the amount of credit awarded, and how credits are applied. At some colleges, AP scores transfer directly to credit hours. At others, your exam scores allow you to “place out” of certain course requirements, even if they do not give you actual college credits.
