Is this an AP CSP exam score calculator?

No. It estimates a classroom course grade from categories and weights.

What if the weights do not total 100%?

The tool normalizes by the entered total, but you should verify all weights against the syllabus.

Can I remove a category?

Yes. Set its weight to 0 so it does not affect the result.

Should the Create task count as a class category?

Only if your teacher includes it in the course grade. Classroom policies differ from AP Program scoring.

Does a high class grade guarantee a high AP score?

No. Classroom grading and the AP assessment are related but distinct.

Can I use this for another computer science class?

Yes, after replacing the labels conceptually with your own categories and entering the correct weights.

How to Use This Calculator

Copy category averages and weights from the teacher's syllabus or gradebook. Set an unused category's weight to 0 and confirm the total weight.

Formula & Methodology

The calculator adds each category score multiplied by its weight, then divides by the total entered weight.

Worked example

If the six category weights total 100%, multiply each category average by its decimal weight and add the results.

School gradebooks may use points, dropped scores, reassessment, late penalties, quarter weighting, or custom rounding that this model cannot reproduce.

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