How to Calculate Your Grade
Weighted grades are calculated by multiplying each assignment's grade by its weight, summing all results, and dividing by the total weight:
Weighted Grade = (Grade₁ × Weight₁ + Grade₂ × Weight₂ + …) / Total Weight
Example: Homework (92%, 20% weight), Midterm (85%, 30% weight), Final (78%, 50% weight) → (92×20 + 85×30 + 78×50) / 100 = 83.9%.
Understanding Weighted Grades
Professors use weighted grading to value different types of work differently. A final exam might be worth 30–50% of your grade, while homework may only count for 10–20%.
Common weight distributions include: Homework 20%, Quizzes 15%, Midterm 25%, Final 30%, Participation 10%. Always check your syllabus for the exact weights.
Because finals carry heavy weight, your final exam score can dramatically raise — or lower — your overall grade. Use Mode 2 to find out exactly what you need.

| B | 83–86 | 3.0 |
| B- | 80–82 | 2.7 |
| C+ | 77–79 | 2.3 |
| C | 73–76 | 2.0 |
| C- | 70–72 | 1.7 |
| D | 60–69 | 1.0 |
| F | Below 60 | 0.0 |
Tips to Improve Your Grade
• Focus on high-weight assignments first — a 5% improvement on a 30% final has 3× the impact of the same improvement on a 10% quiz.
• Don't skip homework — homework is often the easiest category to score highly in, and skipping it hurts your grade.
• Prepare thoroughly for finals — since finals are weighted heavily, consistent study throughout the semester pays off.
• Ask for extra credit — some professors offer bonus assignments. Even a few extra points can bump your letter grade.
• Use study groups and tutoring — collaborative learning helps solidify concepts and catch gaps in your understanding.
