About this exam
The AP Environmental Science Exam is a College Board subject exam for high school students who want to demonstrate college-level understanding of environmental systems. It is not a college admissions test: colleges may award credit or placement based on AP scores, but policies differ by institution. Students commonly take it after an AP Environmental Science course, though College Board does not set a formal course prerequisite. The exam emphasizes applying scientific ideas to real environmental questions, not simply recalling definitions.
The exam covers ecosystem structure, energy flow and productivity; biodiversity, evolution and ecosystem services; biogeochemical cycles; and human impacts on land, water, air and climate. Students also interpret data, graphs and environmental scenarios, and evaluate possible solutions. The published format includes multiple-choice questions and free-response questions, with timing and scoring details subject to official updates. Preparation calls for connecting concepts across units, practicing quantitative reasoning, and explaining evidence clearly—not memorizing isolated facts.
How to prepare for the AP Environmental Science Exam
- Use the current AP Environmental Science Course and Exam Description to organize review. Prioritize ecosystem energy transfer, nutrient cycles, biodiversity, island biogeography and conservation, then connect these topics to human environmental impacts.
- Practice interpreting graphs, tables and study results, and review calculations involving rates, percentages and environmental data. Complete timed sets of both multiple-choice and free-response questions, then identify whether errors came from concepts, calculations or reading the prompt.
- For free-response questions, answer every part directly and support conclusions with evidence from the prompt. Review official College Board sample questions and scoring guidelines, and check AP Central for any format or course updates for the 2027–2028 cycle.
