Is 80 a B or B-?
An 80% is a B- on the standard plus/minus grading scale (2.7 GPA) and a B on a standard 10-point scale without plus/minus (3.0 GPA).
Scoring exactly 80.0% places you on the entry threshold of the B letter grade band, indicating above-average academic performance.
How This Is Calculated
On standard US plus/minus scales, the B- interval is defined from 80.0% to 82.9%. An 80.0% score qualifies for a B- and awards 2.7 quality points per credit.
If your school uses a non-plus/minus 10-point system, any score from 80.0% to 89.9% is simply awarded a B (3.0 GPA).
To raise an 80% up to a solid B (83.0%) on a plus/minus scale, you need to gain 3.0 additional percentage points on your overall course grade.
