The letter comes from this scale. Your school's own scale decides your grade. Change any letter or number to match it.

How a weighted grade works
When some work counts more than other work, each grade is multiplied by its weight, the results are added up, and the total is divided by the sum of the weights. With homework 92% (weight 20), quizzes 85% (20), tests 78% (40) and a project of 44 out of 50, which is 88% (20):
(92 × 20 + 85 × 20 + 78 × 40 + 88 × 20) ÷ 100 = 8,420 ÷ 100 = 84.2%.
The working line under the answer shows this sum with your own numbers.
Weights that do not add up to 100
If some work has not happened yet, the weights you type may add up to less than 100. The page then divides by the weights you did type, which gives your grade on the work done so far. For example, if only homework and quizzes are in, it averages those two. To see what you need on what is left, use the final grade calculator.
Points instead of percents
Type points as 44/50 and the page turns them into a percent first. If your class adds up all points with no weights, add up the points you got and the points possible, and use the grade calculator instead.
Letters
The letter comes from the scale under the result. Change it to match your school's scale.
