100-PERCENT (100 Point) SYSTEM

Undergraduate Grade/Mark Average (GPA). In the 100-Percent (100-point) System, the Undergraduate Grade/Mark Average is determined by adding all earned marks for all semesters, dividing that number by the total number of points possible, and multiplying by 100.If the total number of points earned for the eight semesters is 4416 out of a possible 5250 marks. The Undergraduate Grade/Mark Average for this transcript is 4416/5250×100=84.11. The applicant would enter “84.11” in the Undergraduate GPA Grade Average field and -100 percent” in the Undergraduate GPA Scale field.

Junior/Senior (3rd/4th Year) Grade/Mark Average (GPA).
To determine the Junior/Senior (3rd/4th Year) Grade/Mark Average on the 100-point scale, add all the points earned in the 3rd and 4th Years, divide by the total possible points in those years, and multiply by 100. In Figure 1, the Junior/Senior (3rd/4th Year) Grade/Mark Average would be 2246/2600×100=86.38. On the application,this student would enter “86.38” in the Junior/Senior GPA Grade Average field and -100 percent” in the Junior/Senior GPA Scale field.
