Advanced Placement Exam Scores as a Predictor of Performance in Introductory College Biology, Chemistry and Physics Courses

Survey data from 8,594 students in 55 randomly chosen colleges and universities finds that those having passed an AP science exam earn somewhat higher college science grades, but not enough to assume prior mastery. Moreover, half of this performance difference appears to be related to demographics and high school coursework and not to students' AP coursework. (Contains 4 figures, 4 tables and 26 footnotes.)
