Estimate your AP Biology score from multiple-choice and free-response performance.
An AP Biology Score Calculator estimates your AP Biology score from your multiple-choice and free-response performance.
It converts both sections into weighted scores, combines them into a composite result out of 100 and estimates an AP score from 1 to 5.
The AP Biology exam combines a multiple-choice section and a free-response section.
The multiple-choice section contributes 50% of the exam score, while the free-response section contributes the other 50%.
The calculator converts both raw scores into weighted values and adds them together to estimate a composite score out of 100.
The composite score is then used to estimate an AP score from 1 to 5.
Multiple-choice correct: 40 out of 60
Free-response points: 20 out of 34
MCQ weighted score: 33.3
FRQ weighted score: 29.4
Composite score: 62.7
Estimated AP score: 4
AP score cutoffs can vary by exam year and form, so this calculator uses approximate composite-score ranges for planning purposes.
| Estimated AP Score | Approximate Composite Range |
|---|---|
| 5 | 72–100 |
| 4 | 57–71.9 |
| 3 | 42–56.9 |
| 2 | 27–41.9 |
| 1 | Below 27 |
These ranges are estimates and should not be treated as official College Board score cutoffs.
| Section | Maximum Raw Score | Exam Weight |
|---|---|---|
| Multiple Choice | 60 | 50% |
| Free Response | 34 | 50% |
The free-response section includes six questions and contributes half of the estimated exam score.
The calculator uses the total number of free-response points earned across all six questions rather than requiring you to enter each FRQ separately.
Because the entire free-response section is weighted at 50%, stronger FRQ performance can significantly raise your estimated composite score.
| MCQ | FRQ | Composite | Estimated AP Score |
|---|---|---|---|
| 48 / 60 | 25 / 34 | 76.8 | 5 |
| 40 / 60 | 20 / 34 | 62.7 | 4 |
| 30 / 60 | 15 / 34 | 47.1 | 3 |
| 20 / 60 | 8 / 34 | 28.4 | 2 |
