Frequently Asked Questions
What is the format of the AP Environmental Science exam?
The exam has two sections: a multiple-choice section and a free-response section. The 80 MCQs test your knowledge across 99 topics, while the three FRQs require you to analyze data, design investigations, and propose environmental solutions.
How long is the APES exam and how is the time divided?
The exam is 2 hours and 40 minutes long. You will have 90 minutes for the multiple-choice section and 70 minutes for the three free-response questions. Pacing is crucial for completing all questions in both sections.
How are the APES exam sections weighted?
The multiple-choice section accounts for 60% of your score, while the free-response section makes up the remaining 40%. Each of the three FRQs tests distinct skills, such as data analysis or designing investigations, and contributes to this 40%.
What are the key skills I need for AP Environmental Science?
You must master several science practices, including data analysis, mathematical routines, and text analysis. A core skill is proposing and justifying environmental solutions, which requires you to apply scientific principles to real-world scenarios.
How should I use this platform to study for the APES exam?
We recommend a sequential approach for comprehensive preparation. Work through the topics within each of the 9 units, test your knowledge with AP-style quizzes and unit exams, and then assess your readiness with the full-length mock exam.
Can I use a calculator on the APES exam?
Yes, a four-function, scientific, or graphing calculator is permitted on both sections of the exam. It is especially useful for the FRQ that requires you to perform mathematical routines to analyze an environmental problem and propose a solution.
Is there an equation sheet for the APES exam?
No, an equation sheet is not provided for the AP Environmental Science exam. You are expected to know key formulas for concepts like population growth, energy calculations, and trophic levels to solve certain problems on the exam.
What kinds of Free-Response Questions (FRQs) are on the exam?
The exam features three distinct FRQ types. You will be asked to design an investigation, analyze an environmental problem and propose a solution, and perform calculations as part of analyzing a problem and proposing a solution.
What do APES task verbs like 'describe' and 'justify' mean?
These task verbs require specific responses to earn points. 'Describe' asks you to provide the relevant characteristics of a process or concept, while 'justify' requires you to provide evidence to support a claim or explain your reasoning.
What type of data will I need to analyze?
You will be expected to analyze various forms of data presented in tables, charts, and graphs. Key skills include interpreting visual representations of phenomena, identifying patterns and trends, and using data to support scientific claims and solutions.
