Is a 78% an A or a B?

If you've scored a 78% on a test or assignment, you're probably wondering where that falls on the letter grade scale. The short answer is: it's typically a B−.

Most schools in the U.S. use a standard grading system where letter grades correspond to specific percentage ranges. While slight variations exist between institutions, a common breakdown places an A in the 90–100% range, a B between 80–89%, and a C between 70–79%. Within those broad categories, there are pluses and minuses that fine-tune the evaluation.

According to the grading scale referenced here, a score of 78% lands squarely in the B− range. The chart shows that 76–78% corresponds to a B−, worth a 2.67 GPA. This means it's just below a solid B (which usually starts at 79–81%) but still above a C+.

It's worth noting that some schools or professors may use slightly different cutoffs—especially when it comes to pluses and minuses—but generally speaking, you can expect a 78% to be a B−. While it's not quite in the A range, it's still a respectable score, reflecting good understanding with room for improvement.

If you're aiming for an A, a few extra points can make a big difference. But a 78% shows you're on the right track—especially if you take it as motivation to refine your approach next time.
