These big ideas serve as the foundation of the course and will help you create meaningful connections between the units. Revisiting the big ideas and applying them in a variety of contexts will help you develop a deeper conceptual understanding of the subject.
The four big ideas are spread out among nine course units. Let’s look at what these units are:
- Unit 1: The Living World: Ecosystems
- Unit 2: The Living World: Biodiversity
- Unit 3: Populations
- Unit 4: Earth Systems and Resources
- Unit 5: Land and Water Use
- Unit 6: Energy Resources and Consumption
- Unit 7: Atmospheric Pollution
- Unit 8: Aquatic and Terrestrial Pollution
- Unit 9: Global Change
As you journey through the APES course units, you’ll develop skills categorized under seven science practices. These science practices are central to the study and practice of AP environmental science, and you should apply them regularly during your test prep. Remember that all exam questions will ask you to apply one or more of these practices to derive solutions. So, let’s take a look at what these are:
- Concept Explanation
- Visual Representations
- Text Analysis
- Scientific Experiments
- Data Analysis
- Mathematical Routines
- Environmental Solutions

Now let’s talk about the types of MCQs in Section I. The MCQ section is a combination of individual questions and set-based questions.
Individual questions will occur as standalone prompts with 5 answer choices, and you’ll have to pick the correct option from those.
Set-based questions come in a group of multiple questions that relate to one common data point or illustration. There may be 8 to 10 sets of questions, and each set will test you on specific concepts, topics, and skills you’ve learned during your APES course. Let’s learn a bit more about these set-based questions:
- 3–4 sets will be based on quantitative data, like data tables, graphs or charts
- 3–4 sets will be based on qualitative data or information, like representations, models or maps
- 2 sets will be based on text-based sources
Section II: Free-response questions (FRQs)
Section ll includes three free-response questions, and students will have 1 hour and 10 minutes to answer these questions. These answers require paragraph-form answers.

This course offers flexibility, allowing you to pursue a major in either science or social sciences and still earn credits and/or placement.
Does APES suit your skill set and study habits?
Like most AP courses, APES requires a specific set of skills and study interests. The AP Environmental Science course is a science class that also includes history, geography, biology, math, chemistry, and a lot of other topics. You need to memorize concepts, understand issues, analyze problems through data and other information, and deduce solutions to the problems. If you are already good with these, APES can be easy for you to ace!
How does APES fit into your AP class schedule?
When compared to other AP Science courses, AP Environmental Science can initially appear to be the simpler option. However, this course can be hard and isn't for everyone. Before you select APES, consider your existing AP schedule and whether it can accommodate another course. It is always better to score well on fewer subjects than poorly on many. Remember not to stuff yourself with too many AP courses and burn yourself out.
Finally, before you make this choice, talk to your teachers, seniors, guidance counselor, and parents for advice. Remember, a big chunk of your AP success depends on your AP teacher! Knowing the APES course and exam description will also help you decide whether you should opt for it.
Is AP Environmental Science Hard?
More than being “hard”, AP Environmental Science is considered a very broad and heavyweight course. If you want to succeed on the AP Environmental Science exam, you'll want to know how many people pass the test. In 2023, almost 54% of students passed the AP Environmental Science exam with a score of 3 or above, and about 8% scored a 5.
However, numbers are rarely the correct indicators of an exam’s difficulty. A less popular exam will have fewer students taking it, and therefore, the number of students acing it will also be lower. As mentioned above, what you should consider is whether or not AP Environmental Science suits your career interests, skills, and academic abilities. You can always take the test again if your score isn't what you wanted.
