Your class grade is the weighted average of every item: (score₁ × weight₁ + score₂ × weight₂ + …) ÷ (weight₁ + weight₂ + …). Add each assignment or test with its score and weight, and the calculator updates your current grade live — add or remove rows as your syllabus changes.
Most course grades are not a simple average — each assignment, quiz, midterm and the final carries its own weight. This calculator multiplies each score by its weight, sums the weighted points, and divides by the total weight for your running course grade. It works for any weighting scheme, and you can add or remove rows freely.
Add each assignment, test, or category with its score and weight (%). Your current course grade is the weighted average — add or remove rows as your syllabus changes.
Weights don't have to sum to 100 — the calculator divides by the total weight you enter, so partial plans still give a correct running average.
Let each item i have a score sᵢ (0–100%) and a weight wᵢ (%). Your course grade is:
The weights don't need to sum to 100% — the formula divides by whatever total you enter, so a partial plan still gives a correct running average. This is the same weighted-average math used for final-exam planning; the Final Grade Needed calculator inverts it to solve for a target.
Multiply each item’s score by its weight, add those products, then divide by the total weight. That gives the weighted average: (s₁×w₁ + s₂×w₂ + …) ÷ (w₁ + w₂ + …). The Class Grade Calculator does this live as you add or edit rows.
No. The calculator divides by whatever total weight you enter, so a partial plan still gives a correct running average. If your syllabus weights sum to 100% you’ll see that match in the breakdown; if they don’t, the math is still valid for the items you’ve entered.
Add the final as a row with its weight and a 0 (or your best guess) score. The average will reflect the known work plus that placeholder, showing your current standing and what the remaining weight can still move.
They solve opposite questions. The Class Grade Calculator tells you your current weighted average from a list of items. The Final Grade Needed calculator tells you what score you must get on the final to hit a target, given its weight.
