Question 1

How do I calculate my grade with weighted categories?

Accepted Answer

Multiply each category grade by its weight, add the results together, and divide by the total weight. For example: homework 92% worth 20%, midterm 85% worth 30%, final 88% worth 50% gives (92×0.20 + 85×0.30 + 88×0.50) = 87.9%. This calculator does the math instantly and normalizes weights that do not add up to exactly 100%.

Question 2

What letter grade is my percentage?

Accepted Answer

On the most common US scale: A is 93–100%, A− 90–92%, B+ 87–89%, B 83–86%, B− 80–82%, C+ 77–79%, C 73–76%, C− 70–72%, D+ 67–69%, D 63–66%, D− 60–62%, and below 60% is an F. Individual schools and professors may set different cutoffs, so always check your syllabus.

Question 3

Can I mix letter grades and percentages?

Accepted Answer

Yes — type either a percentage (88) or a letter (B+) into the grade field. Letters are converted to the midpoint of their percentage range (a B+ counts as 88.5%), which is the standard convention when exact scores are unknown.

Question 4

What if my weights do not add up to 100%?

Accepted Answer

The calculator normalizes them automatically: each weight is divided by the total, so proportions stay correct. A warning appears so you can check whether a category is missing — for example an ungraded final exam that has not happened yet.

Question 5

How do I find out what I need on the final exam?

Accepted Answer

Leave the final exam row empty here to see your current standing, then use our final grade calculator: it takes your current grade, the final’s weight and your target, and tells you the exact score you need on the final.
