Semester Grade Calculator
Enter your two quarter grades and the weights your school uses, often 40% each with 20% for the semester exam. Add your exam score to see your semester grade, or leave it blank to see the score you need.
How semester grades are calculated
Many high schools combine two quarter grades and a semester exam: semester grade = quarter 1 × weight + quarter 2 × weight + exam × weight. A common split is 40% / 40% / 20%, but some schools use 45% / 45% / 10% or count the exam less.
Example: quarters of 88% and 82% with an exam of 75%: 88 × 0.4 + 82 × 0.4 + 75 × 0.2 = 35.2 + 32.8 + 15 = 83%.
The exam score you need
Leave the exam score blank and set the semester grade you want. The calculator works out the exam score needed: with 88% and 82% and a goal of 85%, you'd need 85% on a 20% exam.
Semester Grade Calculator FAQs
How much does the semester exam count?
Often 20%, with the two quarters 40% each, but it varies by school and district. Check your student handbook and enter your school's weights.
What if my school uses different weights?
Enter them in the weight boxes. The calculator works with any weights, and they don't need to add up to 100: it scales them for you.
Can I work out a quarter grade too?
Yes. Use the categories tab: enter each category in your gradebook with its weight and your average to get your current grade.
