A major GPA is a credit-weighted average for a defined subset of courses. It may include only courses with the department code, all courses required for the degree, or upper-division work. There is no universal selection rule.
Define the course set first
Check the degree audit, catalog, department handbook, or application instructions. Ask whether prerequisites, supporting math or science, electives outside the department, transfer courses, and repeated classes count.
Calculation
Worked example
| Included course | Grade | Points | Credits | Quality points |
|---|---|---|---|---|
| Research Methods | A- | 3.67 | 3 | 11.01 |
| Major Seminar | A | 4.00 | 3 | 12.00 |
| Statistics | B+ | 3.33 | 4 | 13.32 |
| Total | 10 | 36.33 |
How to report it
Do not label a self-calculated number as official. If an employer asks for major GPA and the transcript does not show one, state that it is a self-calculated estimate and be prepared to explain the included courses.
Audit the selected courses
Create two columns before doing any arithmetic: included and excluded. Record the policy reason beside every borderline course. A cross-listed class, required statistics course, internship, or transfer elective can look relevant while falling outside the department's definition. This small audit makes the estimate reproducible and prevents a favorable grade from being included only because it improves the result.
If the definition changes by purpose, calculate separate labeled estimates for the department and the outside application.
Major GPA is not science GPA
A biology major GPA may follow department degree requirements. An AMCAS BCPM GPA follows AAMC course classifications. The selected course sets can differ.
