Prerequisite Issues

All mathematics (MATH) and statistics (STAT) courses have prerequisites that must be satisfied. Courses taken in high school do not satisfy prerequisites. When you register for a mathematics or statistics class, the university may temporarily accept your enrollment. However, to remain enrolled you must satisfy the prerequisite with appropriate ACT, SAT, or MSU Math Placement Exam (MPLEX) scores, or with college credit for the appropriate prerequisite course. A summary of the ACT, SAT and MSU Math Placement Exam scores required for the department's entry level courses is maintained at the following link:

Please be aware that Montana State University - Bozeman accepts this exam only. If you have taken another math placement exam at another University, including another MUS school, it is non-transferable to MSU.
