To find the grade percentage for 8 wrong out of 30, first calculate the number of correct answers, which is 30 - 8 = 22. Then, divide the number of correct answers by the total number of questions: 22/30 = 0.7333. To convert this to a percentage, multiply by 100, resulting in approximately 73.33%. Therefore, the grade is about 73%.

What is your grade if you go 8 out of 40 wrong?

80%


How do you calculate your grade on a 40 question test?

On a 40-question test, every question is worth 2.5% (100 ÷ 40). The quickest way is to count the questions you got wrong: Grade = 100 − (number wrong × 2.5) 2 wrong → 95% 4 wrong → 90% (usually the lowest A) 6 wrong → 85% 8 wrong → 80% (usually the lowest B) 12 wrong → 70% (usually the lowest C) If some questions are worth more points than others, use points instead: points earned ÷ points possible × 100. Here’s a full 40-question grade chart (onlinegradecalculators) with every score from 0 to 40 wrong, plus a printable version.
