Introduction: Calculating weighted grades is essential for determining the overall performance in a course where different assignments or exams carry different weights. This weighted grade calculator simplifies the process, providing an efficient way to compute your final grade.

Formula: The weighted average is calculated by multiplying each grade by its corresponding weight, summing up these products, and then dividing by the total weight. The formula is as follows:

Weighted Average = (Grade1 * Weight1 + Grade2 * Weight2 + ... + GradeN * WeightN) / Total Weight

How to Use:

- Enter your grades in the "Enter Grades" field, separated by commas.
- Enter the corresponding weights in the "Enter Weights" field, separated by commas.
- Click the "Calculate" button to obtain the weighted average.

Example: Suppose you have grades of 90, 85, and 75 with weights of 0.3, 0.4, and 0.3, respectively. Enter "90,85,75" in the grades field and "0.3,0.4,0.3" in the weights field. Click "Calculate" to get the weighted average.

FAQs:

- Q: Can I use this calculator for any grading system? A: Yes, the calculator is flexible and can be used with any grading scale.
- Q: What should I do if the number of grades doesn't match the number of weights? A: The calculator will prompt you with an alert. Ensure both lists have the same length.
- Q: Can I use percentages for grades and weights? A: Absolutely, the calculator works with both percentages and decimal values.
- Q: Is there a limit to the number of grades and weights I can input? A: The calculator is designed to handle a reasonable number of inputs, but excessively long lists may impact performance.
- Q: Can I use negative weights or grades? A: The calculator does not restrict input values, but using negative weights may yield unexpected results.
