University of Pretoria converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is rounded to the nearest 2 decimal places. Points run from 0.0 up to 100.0, so a higher average is a better result. The scale has no plus/minus steps, so every grade in a band is worth exactly the same number of points.
What gets left out of the average
49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, and 0 work the other way: they earn no credit but are still counted in the average at 49.0, 48.0, 47.0, 46.0, 45.0, 44.0, 43.0, 42.0, 41.0, 40.0, 39.0, 38.0, 37.0, 36.0, 35.0, 34.0, 33.0, 32.0, 31.0, 30.0, 29.0, 28.0, 27.0, 26.0, 25.0, 24.0, 23.0, 22.0, 21.0, 20.0, 19.0, 18.0, 17.0, 16.0, 15.0, 14.0, 13.0, 12.0, 11.0, 10.0, 9.0, 8.0, 7.0, 6.0, 5.0, 4.0, 3.0, 2.0, 1.0, and 0.0 points respectively, so a failed course pulls the average down while adding nothing to your progress.
How this semester rolls into your CGPA
UP states GPA is calculated by multiplying each module final mark by the module credit value, summing those values, and dividing by the total credits enrolled. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are rounded to the nearest 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
