The math: score = right answers ÷ 10 × 100. Each question is 100 ÷ 10 = 10 percentage points, so every wrong answer takes 10 points off a perfect 100%. Letters use the common 90/80/70/60 scale with no rounding up; your teacher may use different cutoffs, plus and minus grades or a curve, so check your school’s grading policy.
