A grade-point average (GPA) is calculated on the basis of the following quality points: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1, F = 0. The grades of CR, NC, I, W, and AU do not enter into the computation of the grade-point average. The GPA is computed on the basis of all courses taken at St. Mary's College for which a letter grade has been received. The grade-point average is computed on both a semester-by-semester basis and on a cumulative basis. Transfer credits are excluded from the GPA computation.
