**Introduction:** Understanding how grades are calculated, especially in platforms like Powerschool, is essential for students aiming to track their academic performance accurately. This calculator simplifies the process, allowing you to calculate your grades with different weights for assignments.

**Formula:** The calculator uses a weighted average formula. Each assignment grade is multiplied by its corresponding weight (expressed as a percentage), and the sum of these weighted grades is divided by the total weight.

**How to Use:**

- Enter your assignment grades separated by commas in the "Enter Assignment Grades" field.
- Enter the weights corresponding to each assignment (in percentages) separated by commas in the "Enter Weights" field.
- Click the "Calculate" button.
- The calculated grade will be displayed instantly.

**Example:** Suppose you have assignment grades of 85, 92, and 78 with weights of 20%, 30%, and 50%, respectively. Enter them as "85,92,78" and "20,30,50" in the respective fields, and the calculator will provide your calculated grade.
