How It Works
The weighted grade is computed by summing the products of each score and its percentage weight: $\text{Score}_{weighted} = \sum (\text{Grade}_i \times \text{Weight}_i)$. If total weight is less than 100%, the result is normalized: $\text{Grade}_{normalized} = \frac{\text{Score}_{weighted}}{\sum \text{Weight}_i} \times 100$.
Formula Used
Weighted Score = ∑ [Grade % × Assignment Weight %] / ∑ Assignment Weight %
This computes your overall grade by weighting scores by their category importance. If the category weights do not sum to 100%, the result is normalized by dividing by the total weight.
Worked Example
Here is a step-by-step example of how these values are calculated:
Homework
90% (grade) @ 40% (weight)
Exams
80% (grade) @ 60% (weight)
Result: Weighted grade: `90*0.4 + 80*0.6 = 84.00%` (Letter grade: B).
Frequently Asked Questions
What happens if total category weights do not equal 100%?
The calculator automatically normalizes the grade. It scales the categories relative to each other so that their ratios are preserved, showing what your grade represents out of the current work completed.
How can I calculate what I need on my final exam?
Set up your categories with current scores, and add a 'Final Exam' category with its weight (e.g. 20%). Alter the final score slider until the weighted class grade reaches your target letter grade.
