How grading works at Carnegie Mellon University (undergraduate)
Carnegie Mellon uses a letter-grade system it calls the Quality Point Average (QPA) rather than "GPA," on a 0.00–4.00 scale for undergraduates — see the Grade Scale Reference above for the exact grade points. This standard applies to "all students classified as seeking an undergraduate degree and special students taking undergraduate courses." Carnegie Mellon maintains a separate, higher-ceiling scale for graduate students that does not apply to undergraduates.
Carnegie Mellon's failing grade is R, not F — the university does not issue an F grade. There is no A+ and no plus or minus grades at all on the undergraduate scale.
Several other notations appear on Carnegie Mellon transcripts but carry no quality points and are not factored into your QPA: P (Passing), N (Not Passing), O (Audit), W (Withdrawal), I (Incomplete), and AD (credit for work completed at another institution or by examination).

How your QPA is calculated at Carnegie Mellon
Carnegie Mellon measures coursework in units, not credit hours — three units are the equivalent of one traditional semester credit hour. Your Quality Point Average is calculated as: units earned for a course × the Quality Point Value of the grade received = quality points for that course. Total Quality Points divided by Total Units Factorable equals your QPA.
Worked example printed by Carnegie Mellon: 11 units of A (44 quality points) + 10 units of R (0 quality points) + 9 units of B (27 quality points) + 9 units of C (18 quality points) + 9 units of D (9 quality points) = 48 total units and 98 total quality points. 98 ÷ 48 = a QPA of 2.04.
Grades of I (Incomplete), P (Pass), and W (Withdrawal) are not awarded quality points and are not counted as factorable units in your QPA. The same procedure is applied to every grade you've earned at the university to calculate your Cumulative QPA.
Repeating a course: if you repeat a course, all grades — the original and every repeat — are recorded on your official transcript and calculated into your QPA, regardless of whether the first grade was passing or failing. Only one set of units counts toward your graduation requirements.

Dean's List and University Honors at Carnegie Mellon
Undergraduate students who meet their home college's academic requirements are added to that college's Dean's List each semester, noted on the transcript. Each college sets its own Dean's List qualification requirements. Only degree-seeking undergraduates are eligible — non-degree students are not.
Some candidates for undergraduate degrees are named to the University Honors List in recognition of exemplary academic achievement. Each undergraduate college selects its own honorees, typically based on a cumulative QPA greater than 3.5 and/or faculty recommendation.

How transfer and cross-registration credit affects your QPA
Courses you take directly at Carnegie Mellon, and courses taken through the university's cross-registration program, have their grades recorded on your transcript and factored into your QPA.
Courses transferred in from other institutions are recorded on your transcript showing where the course was taken, but without a grade — they are not factored into QPA calculations, academic actions, or honors.

What is Carnegie Mellon's lowest passing grade?
The lowest passing grade for undergraduates is D (1.00 quality points). Carnegie Mellon's failing grade is R (0.00 quality points) — the university does not use an F grade.

Do plus and minus grades count toward an undergraduate QPA?
No. Carnegie Mellon's undergraduate scale has no plus or minus grades and no A+. Even if you earn a +/- grade in a graduate-level course, it "will automatically convert to the corresponding letter grade" before it's factored into your QPA — so a plus or minus grade can never appear in an undergraduate's QPA.

What happens if you don't finish the work for an Incomplete grade?
When you're given an I (incomplete), your instructor must specify what's required to complete the course and set a default letter grade to apply if no further work is submitted. You must finish the required work by the end of the following academic semester, or sooner if agreed in advance. If your instructor doesn't record a permanent grade by the last day of that semester's exam period, Enrollment Services will administratively assign the default grade.

Is Carnegie Mellon's QPA the same as a GPA?
Yes, in substance — Carnegie Mellon's own term for its grade point average is QPA (Quality Point Average), calculated the same way a GPA is calculated elsewhere: quality points earned divided by units factored.

Does withdrawing from a course affect your QPA?
No. A W (withdrawal) grade carries no quality points and is not factored into your QPA. After the deadline to drop a course, withdrawing by the end of the 10th week of class results in a W on your academic record.
