Most classes are graded based on several categories:

- Homework
- Tests or Quizzes
- Classwork
- Final exam etc.

Each category is worth a percentage of your overall grade.

**USE NUMBERS TO DECIDE YOUR FINAL GRADE FORMULA**

Determine ahead of time the weight given to each of the sections of your grade book. Here’s an example:

Tests 50% Quizzes 25% Project 25%

Using these percentages, this is how I would figure out a student’s grade:

Tests = 86% = 86 X 2 = 172 (Tests are worth twice as much as the other two, therefore, doubled) Quizzes = 79% = 79 X 1 = 79 Project = 92% = 92 X 1 = 92 172 + 79 + 92 = 343 divided by 4 (4 parts, Tests twice, Quizzes, Project) = 85.75 = 86 = "B"

Here’s a much more complicated example, using possible percentages and an imaginary student’s grades:

Tests 30%: student score of 80% = 80 X 3 parts = 240 Quizzes 30%: student score of 90% = 90 X 3 parts = 270 Project 20%: student score of 75% = 75 X 2 parts = 150 Homework 10%: student score of A- = 92% = 92 X 1 part = 92 Class participation 10%: student score of C = 75% = 75 X 1 part = 75 Total = 240 + 270 + 150 + 92 + 75 = 827 divided by 10 parts = 82.7 = 83 = "B"

This seems like a lot of work, sure. BUT IT IS WORTH IT. Plus you can really get the hang of it after just a few times using it. It’s worth it because the system is **FAIR** and **DEFENDABLE**. Remember before, how we highlighted that the grade has to be justified and explained? This comes from all angels, be it parents, teachers, students or administrators! Now, here’s a system that does that for you! As you are beginning to understand grading systems, weights, percentages and learning, a system to decipher a final grade is the ultimate tip.
