How to use it

Use the block you need: a single score, several weighted items, or the final-exam goal.
Enter percentages or points.
Read the result and the letter grade.

Examples

42 / 50 = 84% (B)
Homework 90% weight 20 + Exam 80% weight 80 → 82%
Current 82%, final worth 30%, target 85% → need 92%.

Letter grades use a common US scale (A 90+, B 80+, C 70+, D 60+). Your school may use a different one. For the weighted grade, weights do not have to add to 100; the result is scaled to the weights you enter.
