📐 How does this work?

Most class grades are made up of several categories: homework, classwork, tests/quizzes, and the final exam. Each category is worth a percentage of your overall grade. Because the final exam isn't scored until the end, the other categories are scaled up to fill the weight reserved for the final.

The core formula for what you need on the final is:

Required = ( Goal − Current × (1 − Final Weight) ) ÷ Final Weight

For example: You have 82%, want 85%, and the final is worth 20%:

Required = ( 85 − 82 × (1 − 0.20) ) ÷ 0.20 = ( 85 − 65.6 ) ÷ 0.20 = 97%

After taking the final, your overall grade is:

Overall = Final Weight × Final Score + (1 − Final Weight) × Grade Before
