 GRADE  POINT AVERAGE (GPA)
                  The overall performance of each  student during an entire semester shall be determined by means of a weighted  grade point average, obtained by awarding credit points in respect of each  course multiplied by the numerical value of the grade obtained as stated above.  The weighted grade point attained by a student in a particular course is the  students’ grade point multiplied by the units attached to the course.
                  The overall performance of a  student during an entire semester shall be determined by means of a weighted  grade point average obtained as a sum of weighted grade point of the student  (from the set of courses) divided by the total number of units contained in the  courses concerned.
                  GPA  (semester grade average = Total grade points / Total course units    
                    For example:
