This option provides a two- or three-term transition for students with three full years of high school mathematics. MAT31X/40X/41X or MAT31X/32X/40X, each a three-term, highly accelerated course, covers a vast breadth of precalculus topics and ends with an introduction to differential calculus. The pace is demanding and the problems that students will encounter are challenging. For students who have completed a study of precalculus mathematics, some topics will be familiar, though likely presented in novel contexts; other ideas and techniques will be new. Open to 9th and 10th graders only, through strong performance on placement tests and approval of the department. Meets during the reserve format.
