Is this the same as an AP Exam score calculator?

No. It estimates a classroom percentage grade from assignment categories, not the AP Exam's 1–5 score.

What if my weights do not total 100%?

The calculator normalizes by the total entered weight, but you should verify the values against your syllabus.

Can I ignore an unused category?

Yes. Set its weight to 0. Its score will not affect the result.

Can this model a points-based gradebook?

Not exactly. Convert each group to an average and weight, or use a dedicated points-based grade calculator.

Does an A in the class guarantee a high AP score?

No. Classroom grading and the standardized AP Exam measure performance differently.

How to Use This Calculator

Enter your current category averages and copy the category weights from your teacher's syllabus or gradebook. The weights should total 100%.

Formula & Methodology

The calculator adds score × weight for every category and divides by the total entered weight, so it remains usable while checking a partial or customized weighting scheme.

Worked example

With category weights totaling 100%, multiply each category average by its decimal weight and add the results.

Teachers may use points, dropped assignments, curved tests, replacement grades, quarter weighting, or policies that a simple category model cannot reproduce.

Use the official syllabus and school gradebook as the authoritative source. This tool is not affiliated with College Board or your school.
