Typical College Course
- Exams (Midterm + Final)40%
- Homework/Assignments25%

- Participation10%
- Final Project10%
Typical High School Class
- Tests50%
- Homework20%

Example Calculation
Let's say you have the following grades:
| Category | Weight | Your Score | Weighted Score |
|---|---|---|---|
| Exams | 40% | 85% | 34.0 |
| Homework | 25% | 92% | 23.0 |
| Quizzes | 15% | 88% | 13.2 |
| Participation | 10% | 95% | 9.5 |
| Project | 10% | 90% | 9.0 |
| Total | 100% | — | 88.7% |
Formula: (85×0.40) + (92×0.25) + (88×0.15) + (95×0.10) + (90×0.10) = 88.7%
Standard Letter Grade Scale

Frequently Asked Questions
How do I calculate my grade in a class?
To calculate your grade, multiply each assignment score by its weight (percentage of final grade), sum all weighted scores, and divide by the total weight. For example: (90×30% + 85×30% + 80×40%) / 100% = 84.5%. Most syllabi list the weight of each category (exams, homework, quizzes, etc.).
How do weighted grades work?
Weighted grades assign different importance to different assignments. For example, if exams are worth 40% and homework is worth 20%, your exam scores impact your final grade twice as much as homework. This system allows teachers to emphasize mastery of material (exams) over practice (homework).
What grade do I need on my final to pass?
Use the formula: Required Final = (Desired Grade - Current Grade × Current Weight) / Final Weight. For example, if you have 80% with 70% of coursework done and want 85%, you need: (85 - 80×0.7) / 0.3 = 96.7% on the final. Use our Final Grade Calculator for easy calculation.
Does extra credit affect my grade calculation?
Extra credit policies vary by teacher. Some add it directly to your total points, others add it to specific categories. Check your syllabus or ask your teacher how extra credit is calculated. In most cases, extra credit can push your grade above 100% in a category.
