Purpose: It helps students determine their current standing in a course where different assignments/exams carry different weights.

2. How Does the Calculator Work?

The calculator uses the weighted average formula:

\[ G = \frac{\sum (w_i \times g_i)}{\sum w_i} \]

Explanation: Each grade is multiplied by its weight, summed together, then divided by the total weight.

3. Importance of Weighted Grades

Details: Most college courses use weighted grading where exams, homework, and projects contribute differently to your final grade.
