With the approval of the academic dean and the department concerned, students may pay a fee and take a proficiency examination in courses offered by the faculty. Degree credit is given for grades of A and B. For courses passed by proficiency exam, the grade is not computed in the cumulative grade-point average. Proficiency examinations ordinarily are not allowed after failure in a course or in courses where the principal content is laboratory or creative work. Proficiency examinations may not be taken in English composition, military education, minicourses, or independent study courses.
