Final Grade Formula

You have to know the current grade, grade you want, and final exam weight to check the final grade value.

The final grade formula is F = [G - ((1 - w) x C)]/w


F is the final exam garde

C is the current grade

G is the grade you want

w is the weight of the final exam in decimal form

How to Calculate Final Grade Score?

The following are the simple guidelines to calculate the final exam grade score.

  • Check desired grade, current grade, and final exam weight.
  • Subtract the decimal form of the final exam weight from 1 and multiply it by current grade.
  • Subtract the product from the desired grade score.
  • Finally, divide the difference by the decimal form of the final exam weight.
  • The obtained result is the score you have to gain.


What is the final exam garde? If my current grade score is 70%, desired grade score is 78%, final exam weightage is 70%.


Given that,

Current grade C = 70

Desired Grade score G = 78

Final exam weight w = 70/100 = 0.7

Final exam grade formula is F = [G - ((1 - w) x C)]/w

Place the values in the formula

F = [78 - ((1 - 0.7) x 70)]/0.7

= [78 - (0.3 x 70)]/0.7

= [78 - 21]/0.7

= 57/0.7

= 81.42

Therefore, the final grade score is 81.42%.
