The exam at a glance

Section I - Multiple Choice

50% of score

60 questions90 minutes

Discrete questions plus sets tied to experiments, models, and data. No penalty for wrong answers.

Section II - Free Response

50% of score

6 questions90 minutes

Two long FRQs followed by four short FRQs. Each answer is scored against a task-specific rubric.

Free-response breakdown

Six questions, scored on task-specific rubrics. The two long FRQs carry most of the section's points.

1

Interpreting & Evaluating Experimental Results with Graphing

Design or evaluate an experiment and construct a graph from the data provided.

Long8–10 pts
2

Interpreting & Evaluating Experimental Results

Analyze an experiment, justify a claim, and predict outcomes under new conditions.

Long8–10 pts
3

Scientific Investigation

Describe a method, identify a variable, and justify the experimental setup.

Short4 pts
4

Conceptual Analysis

Explain a biological process or relationship using correct reasoning.

Short4 pts
5

Analyze Model or Visual Representation

Read a diagram or model and explain what it shows about a biological system.

Short4 pts
6

Analyze Data

Interpret a table or graph and draw a supported conclusion from the data.

Short4 pts

A 3 means no college credit. A 5 locks it in.

Write one real AP Bio FRQ and see if you're on track.

What the exam covers

Eight units, each weighted by the percentage of multiple-choice questions you can expect on that topic. Natural Selection is always the largest share.

  • U1

    Chemistry of Life

    8–11%
  • U2

    Cell Structure and Function

    10–13%
  • U3

    Cellular Energetics

    12–16%
  • U4

    Cell Communication and Cell Cycle

    10–15%
  • U5

    Heredity

    8–11%
  • U6

    Gene Expression and Regulation

    12–16%
  • U7

    Natural Selection

    13–20%
  • U8

    Ecology

    10–15%

The six science practices

Every question - multiple choice or free response - tests one of these. FRQs lean on argumentation and data analysis.

  1. 1Concept Explanation25–33%
  2. 2Visual Representations16–24%
  3. 3Questions & Methods8–14%
  4. 4Representing & Describing Data8–14%
  5. 5Statistical Tests & Data Analysis8–14%
  6. 6Argumentation20–26%

Exam day essentials

Four-function or scientific calculator

Graphing calculators are permitted. The exam supplies a formula and equations sheet - don't memorize it.

3 hours total, with a short break

90 minutes for multiple choice, then 90 minutes for six free-response questions.

Paper-and-pencil exam

You write FRQs in a lined response booklet. Only work inside the booklet is scored.
