How to Calculate Grade Percentage

The following formula is used:

Grade (%) = ((Test Questions - Wrong Answers) ÷ Test Questions) × 100

Example 1:

Find the grade (%) for:

  • Total Test Questions = 32
  • Wrong Answers = 5

Apply the values in the formula:

= ((32 - 5) ÷ 32) × 100

= (27 ÷ 32) × 100

= 0.84375 × 100

= 84%

Example 2:

Calculate the grade (%) for:

  • Total Test Questions = 70
  • Wrong Answers = 18

= ((70 - 18) ÷ 70) × 100

= (52 ÷ 70) × 100

= 0.7428 × 100

= 74%
