An 84 percent is a B on the standard grading scale used by most American schools. On a 4.0 GPA scale, a straight B translates to 3.0 grade points per class. That said, your exact letter grade depends on whether your school uses plus/minus grading, which can shift an 84 into slightly different territory.
Where 84 Falls on the Standard Scale
The most common grading system in the United States breaks letter grades into 10-point ranges. Under this system, the B range covers 80 through 89, placing an 84 squarely in the middle. Here is how the full scale typically looks:
- A: 90–100 (4.0 GPA)
- B: 80–89 (3.0 GPA)
- C: 70–79 (2.0 GPA)
- D: 65–69 (1.0 GPA)
- F: Below 65 (0.0 GPA)
College Board publishes this as one commonly used conversion, but notes that schools may calculate GPA differently and use different grade cutoffs. Always check your own school’s grading policy if precision matters for your transcript.
How Plus/Minus Grading Changes Things
Many colleges and some high schools break each letter grade into three tiers using pluses and minuses. When a school uses this system, the B range (80–89) often splits into B- (80–82), B (83–86), and B+ (87–89). Under that breakdown, an 84 still lands as a B, typically worth about 3.0 on the GPA scale.
The exact cutoffs vary. Some schools set B- at 80–83, which would push an 84 into the B tier at those schools as well. Others draw the line at 84 for the start of a B. The difference between a B- (usually 2.7 GPA points) and a B (3.0 points) can matter when your cumulative GPA is calculated across many classes, so it is worth knowing where your institution draws the line.
What an 84 Means for Your GPA
If your school does not use pluses and minuses, every grade in the 80–89 range earns the same 3.0 points per class. An 84 and an 89 carry identical weight. Your cumulative GPA is the average of all your classes’ grade points, sometimes weighted by credit hours. So a 3.0 in a three-credit course contributes more to your overall GPA than a 3.0 in a one-credit course.
At schools that do use plus/minus grading, a B (84) at 3.0 points sits comfortably above average. For context, a 3.0 GPA meets the minimum threshold for many scholarships, honors societies, and graduate program requirements. It is not a borderline grade in most academic settings.
When an 84 Might Not Be a B
Not every institution follows the standard 10-point scale. Some professors set their own grading curves, where an 84 could be an A in a difficult course or a B- in a lenient one. Curved grading is especially common in college-level science, engineering, and math courses where raw scores tend to be lower.
A handful of schools also use 7-point or other nonstandard scales, where an A starts at 93 or 94 instead of 90. On a 7-point scale, an 84 would fall in the low B or even high C+ range. If your school’s syllabus lists a grading breakdown, that document overrides any generic conversion chart.
