Average = Σ(Grade × Weight) ÷ Σ(Weights). Assignments with higher weights have more impact on the final grade.

Assign weights based on syllabus: quiz = 1, homework = 1, midterm = 2, final = 3. Match your course weighting.

Enter percentage grades (0-100) for each assignment. Name field is optional for organization.

Results show letter grade: A (90+), B (80-89), C (70-79), D (60-69), F (below 60).

Add or remove assignments as needed. The average recalculates automatically.

Enter current grades to calculate your running course average and predict final grade.

Calculate what score you need on the final to achieve your target grade in the course.

Verify your professor's grade calculation by inputting your grades with course weights.

Combine quizzes, homework, projects, and exams with different weights into one average.

Track your grade progress throughout the semester. Update as new grades come in.

Experiment with hypothetical grades to see how they would affect your average.
