The weighted grade calculators for Broward County (BCPS), Howard County (HCPSS) and Arizona State University combine your category scores and weights into one percentage, show the letter grade on that school’s own scale, and work out the score you need on your final exam to reach a target grade.

The curve tools show how a test score changes under the most common curving methods. The grade curve calculator compares flat points, the square root (Texas) curve, highest-score ratio and multiplier curves, and the bell curve calculator turns a score, class mean and standard deviation into a z-score, percentile and letter grade.

Frequently Asked Questions

How do I calculate my weighted grade?

Multiply each category’s percentage by its weight, add the results, and divide by the total weight. For example, 90% homework worth 40% and 80% tests worth 60% gives (90 × 0.4) + (80 × 0.6) = 84%.

How do I figure out what I need on my final exam?

Use: needed = (target − current × (1 − w)) ÷ w, where w is the final’s weight as a decimal. With an 85% current grade, a 20% final and a 90% target, you need (90 − 85 × 0.8) ÷ 0.2 = 110%, so a 90 is out of reach without extra credit.

What is a square root curve?

A square root curve takes the square root of your percentage and multiplies it by 10. A 64 becomes 80 and an 81 becomes 90. It raises low scores the most and never pushes anyone above 100.
