About Grade Calculator
Enter each assignment's score, points possible, and syllabus weight to see your current weighted grade. Then the final-exam solver answers the perennial question: given the final's weight and the overall grade you want, what score do you need on it? Answers above 100% or at zero are called out plainly.

Frequently asked questions
How do I calculate what I need on the final exam?
The formula is (target − current × (1 − w)) ÷ w, where w is the final's weight as a decimal. With an 85% current grade, a final worth 30%, and a 90% target: (90 − 85 × 0.7) ÷ 0.3 = 101.7% — in that case the target isn't reachable.
What does it mean if the required final score is over 100%?
The target grade is mathematically out of reach on the final alone — even a perfect score won't get you there. Your options are extra credit, regrades on earlier work, or picking a lower target to see what's actually attainable.
How does weighted grading work?
Each assignment's percentage score counts in proportion to its syllabus weight rather than its point total. Scoring 90% on a homework worth 10% of the course adds less to your grade than 90% on a midterm worth 25%, even if the homework had more raw points.
Can my school or anyone else see the scores I enter here?
No. Everything you type is processed in your browser only — no server receives your scores, so there's no record of the grades or targets you experiment with.
