Some colleges use AP test scores to exempt students from introductory coursework, others use them to place students in higher designated courses, and some do both. Each college's policy is different (see link below), but most require a minimum score of 4 or 3 to receive college credit.he AP curriculum for each of the various subjects is created for the College Board by a panel of experts and college-level educators in that field of study. For a high school course to have the AP designation, the course must be audited by the College Board to ascertain that it satisfies the AP curriculum.
