Frequently Asked Questions

What are the current AP Biology section weights?

The official exam gives 50% to multiple choice and 50% to free response.

Why can I edit the point totals?

Teacher-created and third-party practice tests may use different question counts or FRQ rubrics.

Does this calculator return a 1–5 AP score?

No. It returns a weighted practice-test percentage. Use an exam-grade estimator with appropriate assumptions for a tentative 1–5 result.

Should all FRQs have equal point values?

Use the actual scoring guide. Long and short AP Biology questions may have different available points.

Can I use this for a classroom unit test?

Yes, provided you enter the test's actual totals and the weights your teacher uses.
