Formula used

The weighted average grade is calculated using: Weighted Average = Σ(grade × weight) ÷ Σ(weight).

Grade is converted to a percent when you use letter or GPA mode.
Weight can be credits, points, or percentage share.
Normalization treats weights as relative and scales them to 100%.
Drop lowest removes the items with the smallest contributions.

Letter conversion uses common midpoints (A=95, B=85, C=75). GPA mode estimates percent by typical band midpoints, then converts back for reporting.
