What is a B+ grade worth?
A B+ is worth 3.3 grade points on the standard US 4.0 scale, and usually maps to a percentage range of 87–89%. That grade-point value is what gets averaged (weighted by credits) across your courses to produce your GPA.
How a B+ affects your GPA
Each course pulls your GPA toward that course’s grade points. A B+ pulls yours toward 3.3: if your current GPA is higher, a B+ drags it down; if it’s lower, a B+ lifts it — and the more credits the course is worth, the bigger the effect. See exactly how with the GPA calculator.
