What Letter Grade is a 60%?

A 60% percentage is the starting point for a “D” grade in most systems, making it a passing score—but just barely.

Letter Grade	Percentage	Is 9/15 (60%) in this range?
C-	70-72%	No
D+	67-69%	No
D	63-66%	No
D-	60-62%	Yes
F	Below 60%	No

A 9 out of 15 (60%) is a D-. It gives you credit for the assignment but signals a need for significant improvement.

Context and Next Steps

While a pass is a pass, a score of 60% indicates that you missed 40% of the material (6 out of 15 points). This is a critical moment to reflect. Was this a particularly difficult topic? Were your study methods effective? This score is a strong signal to review the material and perhaps adopt new study strategies to ensure better results on future, potentially more heavily weighted, assessments.

Frequently Asked Questions (FAQ)

How many more points did I need for a C-?

To get a C- (70%), you would have needed to score 10.5 out of 15 (since 10.5/15 = 0.70). Assuming your teacher only awards whole points, you would have needed a score of 11 out of 15 to clear the C- threshold. This means you were 2 points away.

Will a 9 out of 15 hurt my GPA?

Yes, a D- grade will lower your GPA. A D- grade typically corresponds to 0.7 grade points on a 4.0 scale, which is significantly lower than a C (2.0) or B (3.0). The overall impact depends on the weight of the assignment and your other grades. Check your syllabus and use a GPA calculator to be sure.
