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.

How to Use This Calculator

Enter the raw scores and totals from the exact practice test. Keep 50/50 weights for the current AP Biology exam structure or edit them for a teacher-created test.

Formula & Methodology

Each section percentage is multiplied by its entered weight. The weighted points are divided by the total weight to produce the practice-test percentage.

Worked example

Scoring 42 of 60 MCQs and 28 of 40 FRQ points gives 70% in each section and a 70% weighted practice-test score with equal weights.

Practice materials differ in difficulty, point totals, rubrics, and alignment with the official exam. A teacher may also apply a curve or custom scoring policy.
