What if my weights don't add up to 100%?

That's fine — the calculator scales by the total weight you enter. Leave out the final exam weight from the categories, since it's entered separately.

What if the required score is above 100%?

Then the target can't be reached on the final alone. Try a lower target, or ask about extra credit.

Can I use points instead of percentages?

Convert each category to a percentage first (points earned ÷ points possible × 100).

Does this work for any class?

Yes, as long as your class uses weighted categories. Check the syllabus for the exact weights.

Is the result my official grade?

No. It's an estimate; your teacher's gradebook and rounding rules decide the official grade.

How it was calculated

Σ(weight × score) ÷ Σ(weight): 84.25%
(Target − current × 0.80) ÷ 0.20: 88.00%

Current grade uses only the categories entered, scaled to their combined weight.

How to use the semester grade calculator

Add each category from your syllabus — homework, quizzes, tests, projects — with its weight in percent and your average score in that category.

Enter how much the final exam is worth and the semester grade you're aiming for. The semester grade calculator shows your current grade and the score you need on the final.

For a quick check with just your current grade, try the Final Grade Calculator. See all Grade & GPA Calculators.

How a weighted semester grade works

Current grade = Σ(weight × score) ÷ Σ(weight)
Needed on final = (target − current × (1 − f)) ÷ f

f: Final exam weight as a decimal (20% = 0.20)

The current grade is scaled to the weights you've entered, so it works before every category is graded.

Grades use the common scale: 90–100 A, 80–89 B, 70–79 C, 60–69 D, below 60 F.

Illustrative example

Example: what do I need on the final?

Homework 20% at 92, quizzes 20% at 85 and tests 40% at 80 give a current grade of (18.4 + 17 + 32) ÷ 80 = 84.25%.

With a final worth 20% and a target of 85%, you need (85 − 84.25 × 0.8) ÷ 0.2 = 88% on the final.

Hypothetical figures for illustration only.
