Calculating Your GPA

All applicants for graduate study at Duke University are required to provide an undergraduate grade point average (GPA) on their applications, but we do not require a minimum GPA. Those applicants with a GPA on a 4.0 scale may use that, but those applicants at schools that do not calculate a GPA can provide an estimate using the information below.

International students should also see the note below.

Use the following guidelines when calculating your GPA.

  • The GPA includes all undergraduate coursework completed at the time of submission of the application.
  • If you attended more than one school, the grades from all undergraduate schools must be added together to arrive at the GPA for the bachelor's degree.
  • Do not include courses that were dropped before obtaining a grade or courses that did not award letter grades (e.g. satisfactory/unsatisfactory, pass/fail, credit only). Courses in which failing grades were received must be included, however. Also, if you repeated a course, you must include both grades in your GPA calculation.
  • Do not include graduate level courses that you have completed unless they counted toward your undergraduate degree requirements. (There is a place on the application for you to provide your graduate grade point average.)

The following values are assigned to letter grades when calculating the UGPA.

4.0 = A+, A 2.7 = B- 1.3 = D+
3.7 = A- 2.3 = C+ 1.0 = D
3.3 = B+ 2.0 = C 0.7 = D-
3.0 = B 1.7 = C- 0.0 = F

Step 1. Multiply the grade values (see above) times the number of credit hours. Sample:

Grade  Credit Hours X  Grade Value =  Grade Points
A-           4     X 3.7      = 14.8
B+          3     X 3.3      = 9.9
C-          4     X 1.7      = 6.8
F          3     X 0.0      = 0.0

Step 2. Add the total number of credits (4 + 3 + 4 + 3 = 14) and the total number of grade points (14.8 + 9.9 + 6.8 + 0.0 = 31.5)

Step 3. Divide the total number of grade points by the total number of credits (31.5/14 = 2.25).

Note: Do not combine quarter credit hours with semester credit hours; instead, convert quarter hours to semester hours. Generally one quarter hour = 2/3 semester hour.

Note to International Applicants

The World Education Service website provides helpful information about converting grades to the U.S. system, but we do not require or accept WES conversions.  Applicants from China and India may find these Transcript Guidelines helpful.
