Quarter and exam formula
Semester grade calculator
Combine 2 quarter grades and a final exam with weights that match your syllabus.
Multiply every grade by its weight
Convert each weight to a decimal, multiply it by the matching grade, and add the 3 contributions. A 10% exam cannot change the result as much as a 45% quarter.
The letter estimate uses common US cutoffs. Your school's exact plus and minus thresholds may differ.
