How to Manually Calculate Your Grade

To calculate your grade, you will need to know the total number of questions and the number of answers that you got wrong. Once you have that information, you subtract the number you got wrong from the total number of questions. Then you divide by the total number of questions. Finally, multiple by 100 to find your grade as a percentage.

Grade Percentage Formula

grade percentage = ((total number of questions - number wrong) / total number of questions) x 100

Example Calculation

Here's an example of how you would use the formula to calculate your grade:

Let's say you took a test with 50 questions and got 5 of them wrong.

To calculate your grade, you would plug the numbers into the formula: (50 - 5) / 50 x 100 = 90

So your grade on the test would be 90%.
