The math: score = right answers ÷ 47 × 100. Each question is 100 ÷ 47 = 2.13 percentage points, so every wrong answer takes 2.13 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.
