How semester grades work in U.S. schools
Most American high schools split the year into two semesters, each with two quarters (or three six-week periods in parts of Texas and the South). Your semester grade blends those grading periods with a semester exam. It's the semester grade, not the quarter grades, that earns credit and goes on your transcript.
Semester grade = Σ(period grade × weight) ÷ Σ(weights)
Worked example
Q1 88%, Q2 81%, final worth 20%
So far: (88×40 + 81×40) ÷ 80 = 84.5%.
To finish with a B (80%): (80×100 − 84.5×80) ÷ 20 = 62% on the final. For an A- (90%): (9,000 − 6,760) ÷ 20 = 112%, not reachable.
Presets included
- 2 quarters + final (40/40/20): the most common high school setup.
- 2 quarters + midterm + final: for schools that give a midterm exam each semester.
- 3 six-weeks + exam: three grading periods plus a semester exam (15%).
- College: midterm + final: coursework, a midterm and a cumulative final.
Every name and weight is editable, so you can match your handbook exactly.
From semester grade to GPA
Each semester grade becomes a letter and grade points on your transcript. Enter your semester letters in the high school GPA calculator to see your weighted and unweighted GPA, or in the college GPA calculator for credit-hour courses.
