The average midterm exam score in the United States varies widely depending on the subject, educational level, and institution. According to the National Center for Education Statistics (NCES), the average score for high school students on the ACT exam, a common college admissions test, was a 20.8 out of 36 in 2020. For college students, the average grade on midterm exams can range from a B- to a B+ depending on the difficulty of the course and the rigor of the institution. However, these averages can be misleading as they do not account for the distribution of scores across the student population. For instance, a small group of students may achieve exceptionally high scores, while the majority of students may score lower. Additionally, the grading scale and the difficulty of the exam content can significantly impact the average score.
