Add each graded category with its weight — homework, quizzes, midterms — to see your current course grade. Then use the final exam tool to find the score you need to hit a target.
What score do you need on just the final to reach a target overall grade?
Multiply each category's score by its weight, sum those, then divide by the total weight: weighted grade = Σ(score × weight) ÷ Σ(weight). If homework is 20% at a 90% average and the midterm is 30% at 75%, and those are the only two categories entered so far, the running grade is (90×20 + 75×30) ÷ (20+30) = (1800+2250) ÷ 50 = 81%.
That's normal mid-semester — categories not yet graded simply aren't in the list yet. The calculator divides by whatever total weight you've actually entered, so it always reflects your correct grade for the portion of the course completed so far, not a distorted number assuming ungraded work counts as zero.
Use the second tool: enter your current grade (everything before the final), your target overall grade, and the final's weight as a percentage of the total course grade. It solves final score = (target − current × (1 − weight)) ÷ weight — the algebraic rearrangement of "your current grade times its share of the total, plus your final score times its share, equals your target."
Above 100% means the target isn't mathematically reachable no matter what you score on the final — the current grade and final's weight don't leave enough room. Below 0% (or the tool showing "already locked in") means you've already secured the target grade even with a zero on the final, assuming the rest of the course grade is finalized as entered.
The standard US scale: A 90–100, B 80–89, C 70–79, D 60–69, F below 60. Many schools use plus/minus variants (A-, B+, etc.) or entirely different cutoffs, especially outside the US — check your specific syllabus for the exact scale that applies to your course, since the letter shown here is a common default, not a universal standard.
This page calculates your grade within a single course from its component assignments and exams. The GPA Calculator combines final letter grades across multiple courses, weighted by credit hours, into one overall GPA. Use this page first to find out what grade you're on track for in a specific class, then feed that letter grade into the GPA calculator alongside your other courses.
Worked example: current grade 82% going into the final, target 88% overall, final worth 20% of the grade: needed = (88 − 82×0.8) ÷ 0.2 = (88 − 65.6) ÷ 0.2 = 112% — not achievable, since no exam score exceeds 100%. Lowering the target to 85% instead: (85 − 65.6) ÷ 0.2 = 97% — technically achievable, but only with a near-perfect final.
