NOTE: All courses must be completed with a grade of "C" or better; must have a GPA >2.5; as an advising guideline, we recommend that most MSRs be completed with a "B" or better. While the grade of "C" is acceptable in each course, students earning B's or better have a significantly higher chance of success in upper division science and mathematics courses.
