Officials at Princeton University redefined their grading scale, clarifying what it takes to get each grade.

A+ — Exceptional, significantly exceeds the highest expectations for undergraduate work

A — Outstanding, meets the highest standards for the assignment or course

A- — Excellent, meets very high standards for the assignment or course

B+ — Very good, meets high standards for the assignment or course

B — Good, meets most of the standards for the assignment or course

B- — More than adequate, shows some reasonable command of the material

C+ — Acceptable, meets basic standards for the assignment or course

C — Acceptable, meets some of the basic standards for the assignment or course

C- — Acceptable, while falling short of meeting basic standards in several ways

D — Minimally acceptable, lowest passing grade

F — Failing, very poor performance

There are two key differences between Princeton and Binghamton University, for which no well-defined scale exists: there’s no such thing as an “A+” here, and a “D” in Harpur College will not earn any credit toward a degree or major.
