Weighted grades: score, weight, and remaining work
A weighted grade combines scores according to how much each assessment counts toward the final course grade. For each row, multiply the score percentage by its weight, add those weighted scores, then divide by the sum of the included weights. A test worth 40% therefore affects the overall average more than a quiz worth 10%.
Worked example
Suppose a student earns 90% on work worth 40% and 80% on work worth 60%. The weighted average is (90 × 40 + 80 × 60) ÷ 100 = 84%. The calculator ignores incomplete rows with no valid score and positive weight; use only scores and weights that match your syllabus.
The grade letters shown here use AllCalc’s built-in scale, which may not match your school’s cutoff ranges. The “needed” result is only an estimate for remaining coursework when the weights entered leave a portion of the course ungraded. Confirm the grading policy and all assignment weights in your course syllabus.
Tips for accurate results
List each category with its weight and your current average, such as homework, quizzes, midterm, and final. Weights should add up to 100 percent. To plan ahead, use the target grade option to see what score you need on remaining work.
Common mistakes and limits
The calculation is only as accurate as the weights from your syllabus, and some courses drop the lowest score or curve final grades, which this estimate cannot know. If the required score on the final exceeds 100 percent, ask your instructor about extra credit or other options.
