About the Semester Grade Calculator
Many schools set your semester grade as a weighted mix of your term (quarter) grades and a final or midterm exam. A very common split is 40% for each of the two terms and 20% for the final exam, though your school may weight them differently.
This calculator combines them: it multiplies each term grade and the final by its weight, adds them up, and divides by the total weight — so the weights don't have to add up to exactly 100. Enter your two term grades and your final, adjust the weights to match your syllabus, and you'll get the semester percentage and letter grade.
If your semester is just two terms with no final, set the final's weight to 0 and it averages the two terms by their weights. Everything runs in your browser.
