How it works
When to use it
- Combine weighted categories (homework, quizzes, exams) into a course grade.
- Find the final exam score you need for a target grade.
Formula
Grade = Σ(score × weight) ÷ ΣweightNeeded on final = [target − current × (1 − final weight)] ÷ final weightWorked example
Given: Homework 90 (20%), quizzes 85 (20%), midterm 78 (30%); final worth 30%, target 85
- Current = (90×20 + 85×20 + 78×30) ÷ 70 ≈ 83.43.
- Needed = (85 − 83.43 × 0.7) ÷ 0.3 ≈ 88.67.
Result: You need about 88.67 on the final to finish with an 85.
Reading the result
- Over 100 means the target is out of reach; below 0 means you've already secured it.
Limitations
- Check your syllabus for extra rules such as dropped lowest scores or minimum exam requirements.
