They don't — every grade you type is averaged with its own weight. Delete dropped quizzes from both lists yourself before reading the result.
This tool is weighted: each grade pairs with its own % weight and the total is normalized by the weight sum. For points systems, convert each assignment to a percentage first, giving weights proportional to course points.
Math, not hope: add it as one more grade-and-weight pair and watch the average move. A small weight means a small effect — exactly what the normalization shows.

Grades 85, 90, 78 weighted 20/30/50 give 17 + 27 + 39 = 83.0%. Weights are normalized by their sum, so they don’t need to total 100 — and the headline turns red below 70%.
