AP Environmental Science Exam Format

The AP Environmental Science exam comprises 2 question types, MCQs and FRQs. These questions may appear as standalones or in sets, and some may be accompanied by visuals. Let’s dive into each question type in detail.

Multiple-Choice Questions

Section 1 of the APES exam format accounts for 60% of your total exam score. It consists of 80 MCQs to be answered in 1 hour and 30 minutes. These questions are a mix of standalone and set-based formats. While most of the questions will be standalone, you will find approximately 9 set-based, including: 

  • 3-4 sets include quantitative data, such as data tables, charts, or graphs. These questions mostly evaluate Science Practice 5 (Data Analysis), and can also check your knowledge of other Science Practices 1, 4, 6, or 7 (Concept Explanation, Scientific Experiments, Mathematical Routines, or Environmental Solutions).
  • 3-4 sets include qualitative information, such as models, representations, or maps. These questions assess your understanding of Practice 2 (Visual Representations) but can also evaluate Science Practices 1, 4, or 7 (Concept Explanation, Scientific Experiments, or Environmental Solutions).
  • 2 sets include text-based sources. These questions analyze Science Practices 1, 3, 6, or 7 (Text Analysis, Concept Explanation, Mathematical Routines, or Environmental Solutions).

    The MCQ section will have questions from the 9 units you learn through the APES course. However, certain units are given more weight in the MCQ section, and you will get more questions from them. The table below lists each unit and its respective weight:
Units MCQ Section Weight
Unit 1: The Living World: Ecosystems 6-8%
Unit 2: The Living World: Biodiversity 6-8%
Unit 3: Populations 10-15%
Unit 4: Earth Systems and Resources 10-15%
Unit 5: Land and Water Use 10-15%
Unit 6: Energy Resources and Consumption 10-15%
Unit 7: Atmospheric Pollution 7-10%
Unit 8: Aquatic and Terrestrial Pollution 7-10%
Unit 9: Global Change 15-20%
Did you know?
There is no penalty for incorrect answers on the MCQ section. Don't worry if you're not sure about an answer for 1 of the multiple-choice questions. It's a good idea to guess because you have a 25% better chance of getting a point than scoring nothing!

Our step-by-step guide on how to approach AP Environmental Science multiple-choice questions will help you do just that!

Free-Response Questions

Section 2 of the APES exam format consists of 3 free-response questions, which you complete within the BluebookTM, the digital platform used for the exam. You have 1 hour and 10 minutes to complete this section. It is worth 40% of your total exam score. There are 3 broad FRQ types in this section:

  1. Question 1 requires you to design an investigation based on an authentic environmental scenario depicted by a model/visual representation or quantitative data.
  2. Question 2 requires you to analyze an environmental problem and come up with a solution based on an authentic environmental scenario illustrated by a model/visual representation or quantitative data.
  3. Question 3 requires you to analyze an environmental problem and provide a solution by doing calculations based on an authentic environmental scenario.

What Is Tested on the APES Exam?

In addition to the question types, it's important to understand the skills and topics tested on this exam. The APES exam evaluates your knowledge of environmental concepts and how they can be applied as solutions to real-world problems. The exam tests students on 2 components:

  1. Science Practices

    Science practices are essential for understanding and applying environmental science concepts. Students are expected to use these practices and skills when answering exam questions. You need to master the following 7 science practices for the MCQ and FRQ sections of the APES exam.

    Science Practice MCQ Section Weight FRQ Section Weight
    Practice 1: Concept Explanation 30-38% 13-20%
    Practice 2: Visual Representations 12-19% 6-10%
    Practice 3: Text Analysis 6-8% Practice 3 is not explicitly assessed in the free-response section.
    Practice 4: Scientific Experiments 2-4% 10-14%
    Practice 5: Data Analysis 12-19% 6-10%
    Practice 6: Mathematical Routines 6-9% 20%
    Practice 7: Environmental Solutions 17-23% 26-34%

    Note that questions related to science practices with higher weights will appear more frequently on the exam. For example, you're likely to see more questions related to Practice 1 in Section 1 and Practice 7 in Section 2. These weightings will help you prioritize your study efforts and create an effective plan based on your strengths and weaknesses.

  2. Course Content

    The APES course is structured around 4 overarching Big Ideas and 9 study units. A thorough understanding of the course content is essential for answering questions correctly and earning a strong APES score. If you're planning to take the APES course or exam, it is crucial to familiarize yourself with the full curriculum.

How Is the APES Exam Scored?

The AP Environmental Science exam is graded on a scale of 1 to 5. APES scores of 3 or higher are typically required for advanced placement and/or college credit. Since each college has its own credit requirements, it is a good idea to check the AP credit policy of your prospective colleges well ahead of time.

Double-Check Your Units!
Ensure the units in your calculations and final answers are correct. Proper units keep your work accurate and help you avoid losing points for minor mistakes.

Will the AP Environmental Science Exam be Administered through Paper or Digital Mode?

The AP Environmental Science exam is entirely digital, with students answering MCQs and FRQs using the Bluebook testing app. All responses are automatically submitted once the exam concludes.
