Weighted grade = sum of (category weight × category percent). If categories sum to less than 100%, the tool flags it — most common cause is forgetting the final exam weight. The 'needed on final' formula is: (target − current points earned) / final weight.

My weights don't add to 100 — is that wrong?

Usually yes. Syllabi occasionally reserve small chunks (attendance, in-class quizzes) under 'other' — the tool shows the gap so you can fill it or confirm.

Can I use this for a letter-grade cutoff?

Yes — enter the cutoff (e.g., 90% for an A) as the target. The tool tells you the score you need on the remaining weight to land exactly on that boundary. Remember that most schools round 89.5% up to A, but some don't — check your school's policy.

What about curves or bell-curving?

The tool assumes absolute grading (your 85% is a B). Curved classes depend on the rest of the class's performance, which you can't know until finals are scored — use absolute grading as a worst-case estimate.

What it does

Work out a final course grade from weighted categories (homework 20%, midterm 30%, final 50%, etc.) or figure out exactly what you need on the final to hit a target grade. Essential during exam prep and end-of-semester planning — and the math most students get wrong when they try it in their head.

Example input & output

Input

Homework 20% @ 88%
Midterm 30% @ 76%
Final 50% = ?
Target: B (85%)

Output

Current weighted: 80.4%
Need on final: 91.2%

If the final is unreachable (above 100%), the tool flags it so you can plan realistic targets — or ask the professor about extra credit.

How to use it

Enter each category, its weight, and your current score.
Add the final exam and the target grade.
Read your current weighted grade and the score needed on the final.
Plan study time accordingly.

When to use this tool

Before a final exam — compute exactly what score you need to clinch a target grade.
Mid-semester check-in to see where you actually stand across weighted categories.
Deciding whether to retake an assignment if the weight allows rework.
Comparing grade scenarios (curve vs no curve, drop-lowest vs no-drop policies).

When not to use it

Courses that grade on a curve — you can't compute your final letter until the class is scored.
Pass/fail classes — use the threshold your syllabus specifies, not a percent target.
Courses with a participation 'instructor discretion' category worth 10%+, since that's guesswork.
