What this page will not tell you
The College Board does not publish the raw-score-to-AP-score conversion for AP Bio, or for any other subject, so this page does not print a predicted 1–5. It gives you the composite the College Board actually builds — your points, weighted exactly as it weights them — and what every AP Bio student scored last year.
The AP Biology exam is multiple choice at 50%, free response at 50% of the score. That is 60 multiple-choice questions and 34 free-response points, which the weights turn into a single composite out of 100. In 2026, 71% of AP Bio students scored 3 or higher and 15% scored a 5.

Assumptions
- The College Board publishes no raw-score-to-AP-score conversion for any subject, so no predicted 1–5 is shown. Checked against the Course and Exam Descriptions, AP Central and the official AP Score Scale Table.
- Section weights and multiple-choice counts are each subject's published exam format for the next administration; free-response maximums were counted question by question from the 2025 Scoring Guidelines.
- AP Statistics' free-response maximum of 40 comes from its own exam page ("four 10-point question types"), because its free-response section was rebuilt after the 2025 rubric.
- AP Macroeconomics and AP Microeconomics publish weights of 66% and 33%, which are thirds rounded to whole numbers; they are normalised so a perfect paper scores 100.
- The AP History short-answer maximum is 9, not 12: the paper prints four questions but every student answers three.
- Score distributions are the published 2026 results and describe that year's cohort, not the conversion.
- Subjects scored partly by portfolio or performance task (Computer Science Principles, Seminar, Research, Art & Design) and the world-language exams are not modelled, because the student cannot mark those parts themselves.

How the AP Bio exam is weighted
Sections are weighted, not added up, so a raw point is worth different amounts depending on where you earned it. This is the whole reason a “points out of 94” figure is misleading on an AP exam.
| Section | Maximum | Weight | One point is worth | How that maximum is built |
|---|---|---|---|---|
| Multiple choice | 60 questions | 50% | 0.83 composite | 60 questions, one raw point each. |
| Free response | 34 points | 50% | 1.47 composite | 2 long questions at 9 points and 4 short questions at 4 points. |

What AP Bio students actually scored in 2026
This is the published outcome, not the conversion. It cannot be read backwards to a point threshold — but it is the honest answer to “is this a good paper for this exam?”
| AP score | What it recommends | % of students | At or above | |
|---|---|---|---|---|
| 5 | Extremely well qualified | 15% | 15% | |
| 4 | Very well qualified | 25% | 40% | |
| 3 | Qualified | 31% | 71% | |
| 2 | Possibly qualified | 21% | 92% | |
| 1 | No recommendation | 8% | 100% |

Frequently asked questions
▸What composite do I need for a 5 on AP Bio?
Nobody outside the College Board knows, and that includes every site that prints a number. The conversion is re-set for each year's exam by a standard-setting process, and the College Board publishes neither the process's output nor any past table. What is published is the outcome: 15% of AP Bio students scored a 5 in 2026.
▸How is the AP Bio composite calculated?
Each section is scored out of its own maximum, converted to a fraction, and weighted: multiple choice 50%, free response 50%. This page does that arithmetic with the College Board's own published weights and shows each section's contribution separately.
▸Is the AP Bio exam curved?
No. The College Board states the exams are criterion-referenced rather than norm-referenced: every student who meets the criteria for a given score receives it, however many students that is. What moves between years is the difficulty of the paper, which is why the point threshold moves with it.
▸How many multiple-choice questions are on the AP Bio exam?
60, worth 50% of the exam score. The free-response section is worth the remaining 50% and is marked out of 34 raw points.
▸Does a raw point on one section count the same as on another?
Not usually. Here 60 multiple-choice questions carry 50% while 34 free-response points carry 50%, so one free-response point is worth about 1.8× a multiple-choice question.
