Formula & How It Works
This calculator uses a standard formula to determine your grade percentage. It first calculates the number of correct answers by subtracting the number of wrong answers from the total number of questions.
Correct Answers = Total Questions - Questions Wrong
Then, it uses the following formula to calculate the percentage:
Grade Percentage (%) = (Correct Answers / Total Questions) x 100
The percentage is then converted into a letter grade based on a standard USA grading scale (90-100% = A, 80-89% = B, etc.).
