Normally, a student may obtain credit toward a graduate degree in the Faculty of Science for not more than a 0.5 unit graduate course. Undergraduate students enrolling in a graduate course must, normally, have an 80% average and have completed three years of study. Approval of the instructor and the graduate officer of the department in which the course is offered must be obtained. Credit for the graduate course toward a graduate degree will not be given unless the student attains an A average in her/his major subjects in the fourth year.
