How to read the grading chart
Set the total number of questions above; each row shows the percentage and letter grade for that number correct. The chart uses the standard US scale (A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60). Districts and colleges tweak the plus/minus cutoffs — check your syllabus if you need an exact letter.
Formula
score % = (correct ÷ total) × 100 · letter grade = highest band ≤ score
Example
8 correct of 10 → 80% → B on the standard US scale (B+ if your school starts B+ at 87)
