Semester Grade Calculator
Enter each category's weight and your score to see your weighted semester grade and its letter.
How it works
Most courses don't grade everything equally. Homework might be 20% of your final, the midterm 30%, and the final exam 50%. That weighting is the whole point — a rough homework week hurts far less than a rough final.
For each category, enter what it's worth (its weight) and the score you got in it. The calculator multiplies each score by its weight, adds those up, and divides by the total weight — so it still works even if your weights don't add up to exactly 100.
The result is your weighted semester grade with a letter beside it, updating as you type. It's a quick way to answer 'where do I actually stand?' before grades are posted, or to test what a certain final score would do to your total.
Frequently asked questions
How is a weighted semester grade calculated?
Each category's score is multiplied by its weight, all of those are summed, and the total is divided by the sum of the weights. A 90 in a 50%-weighted final counts far more than a 90 in a 10% quiz.
Do my weights have to add up to 100?
Ideally yes, but this tool divides by whatever weights you enter, so partial inputs still give a sensible running grade. The panel shows your total weight so you can tell if a category is missing.
What letter grade does a score get?
It uses the common scale: 90 and up is an A, 80s a B, 70s a C, 60s a D, and below 60 an F. Your school's exact cutoffs may differ by a point or two.
