Sample data modeled after typical grade distributions in introductory-level college STEM courses at U.S. universities.
Note: Grade thresholds follow a standard 10-point scale. Plus/minus grades are consolidated into letter grade bands. N represents total enrolled students who completed the course.
At 34% of all grades, B is the modal grade in this course. This is consistent with national data showing grade inflation trends where B has replaced C as the most common college grade.
A combined 62% of students earned an A or B, suggesting that the course material and instruction are effectively supporting student learning for the majority of the class.
The 6% F rate is within the typical 5-15% range for introductory STEM courses. Identifying at-risk students earlier through midterm assessments could help reduce this further.
