How this service works
Overall class grade from categories or assignments with scores, maximums and weights, normalizing weights that do not total 100.
Output
Returns the overall percentage grade, letter grade, GPA points (4.0 scale), a breakdown of each item's weight and points contributed, whether weights were normalized, the highest and lowest performing items, and a plain-English summary and verdict.
Example use cases
End-of-semester grade check
“Can you figure out my final class grade? I have: Homework at 90/100 worth 25%, Labs at 48/60 worth 20%, Midterm at 74/100 worth 25%, and Final Exam at 85/100 worth 30%.”
Grade with mismatched weights
“My professor gave these weights but they don't add up to 100 — can you still calculate my overall grade? Participation 10%, Assignments 25%, Project 35%, Final Exam 25%, Quiz 15%. My scores are 9/10, 88/100, 42/50, 78/100, and 14/20.”
Three-category course grade
“I only have three grade categories: Homework worth 40% (I got 185 out of 200), a Midterm worth 25% (scored 67 out of 80), and a Final worth 35% (scored 91 out of 100). What's my overall percentage and letter grade?”
Technical details
Endpoint
GEThttps://grades-calc.x402tookit.com/weighted-grade?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute a weighted overall class grade from multiple categories or assignments with individual scores, maximums, and weights — especially when the weights may not sum to 100 and need automatic normalization. Prefer this over a simple average calculator when category weights differ and you need a letter grade, GPA points, and a per-category breakdown.
Side effects
- Missing required 'items' query parameter returns an error
- Items array exceeds 50 entries may be rejected or truncated
- Malformed JSON in the items array returns a parse error
- All weights set to zero results in undefined normalization
- Scores exceeding the maximum value may produce unexpected percentages
