Harvard College 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 4.0, so a higher average is a better result. The scale uses plus and minus grades, so there are 18 distinct point values rather than a handful of whole steps: A is worth 4.0 and A- is worth 3.67.
What gets left out of the average
CR, PA, SAT, WD, EXT, GNR, SUS, MKP, and MK2 carry no point value at Harvard College, so a course marked with one of them drops out of the division entirely โ it changes neither the top nor the bottom of the fraction. CR, PA, and SAT still earn credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves. E, FL, ABS, NCR, UNS, UEM, and EXLD work the other way: they earn no credit but are still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.
How this semester rolls into your CGPA
Harvard College GPAs are cumulative and based on completed letter-graded courses taken while at Harvard, including failed courses, using the official 4-point transcript scale. 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.
