The calculator will show your final semester grade as:
(85×0.40) + (90×0.40) + (80×0.20) = 87%
That’s a solid B+ or A-, depending on your school’s grading scale.
You multiply each grade by its weight (as a decimal) and add the results. For example, 85% × 40% = 34. Then repeat for the other sections and total them all.
Enter your 1st and 2nd quarter grades and weights, then leave the final exam field blank or try different hypothetical scores to see how it would impact your semester grade.
Yes, if your course uses a similar grading structure (e.g., midterms or papers in place of “quarters”), just treat the inputs accordingly.
Many U.S. high schools use a 40% weighting for each quarter and a 20% weighting for the final exam. Some may vary, so check your syllabus or ask your teacher.
Currently, it shows your numeric grade, but you can refer to your school’s grade scale to match the percentage to a letter grade (e.g., 90–100% = A, 80–89% = B, etc.).
