How to Use the Grading Calculator with Weights
This calculator helps you determine your current grade and what score you need on a final exam to achieve a desired grade, based on weighted assignments.
- Set the number of assignments – Enter the total number of graded assignments (excluding the final exam) in the "Number of Assignments" field. The default is 3.
- Enter assignment scores and weights – For each assignment, input:
- Score (%) – Your percentage grade (0–100).
- Weight (%) – The assignment’s weight toward your total grade (0–100).
- Set your desired final grade – Enter the overall grade you want (0–100) in the "Desired Final Grade (%)" field.
- Set the final exam weight – Enter the percentage weight of the final exam (0–100) in the "Final Exam Weight (%)" field.
- Click "Calculate" – The calculator will show:
- Current Grade – Your weighted average from all assignments.
- Grade Needed on Final – The minimum score you need on the final exam to reach your desired grade.
Note: All scores and weights must be between 0 and 100. The total weight of assignments can be any value (it doesn’t need to sum to 100). If the final exam weight is 0%, the desired grade must equal the current grade exactly.
