AP Environmental Science practice sets

This page provides one canonical AP Environmental Science practice hub with five short sets of 10 original questions each. The sets cover ecosystems, biodiversity, populations, Earth systems, land and water use, energy, atmospheric and aquatic pollution, global change, quantitative data, investigations, and environmental solutions.

Skills covered

  • Explain environmental concepts and processes
  • Analyze data, visual representations, maps, models, and written sources
  • Apply quantitative methods and environmental calculations
  • Design or evaluate an investigation and identify variables and evidence
  • Propose a solution to an environmental problem and justify trade-offs

AP Environmental Science course and exam scope

College Board organizes AP Environmental Science into nine units: ecosystems, biodiversity, populations, Earth systems and resources, land and water use, energy resources and consumption, atmospheric pollution, aquatic and terrestrial pollution, and global change.

College Board’s current exam page describes a fully digital Bluebook exam with individual and set-based multiple-choice questions and free-response tasks involving investigation design, quantitative data, calculations, and environmental solutions. Current calculator and reference-information rules can change, so verify them before test day.

How to use this page

Start with one untimed set to identify a topic gap, then use timed sets to build pacing. For every missed item, identify the scale, units, environmental mechanism, and evidence before solving a new similar problem.

These questions are original supplemental practice. They are not official College Board questions, secure AP Exam content, AP Classroom assignments, a score predictor, or a substitute for current AP policies and course materials.

For current scope and preparation, review the AP Environmental Science course page, the AP Central course overview, the AP Environmental Science exam page, the AP Environmental Science Course and Exam Description, and the AP calculator policy.
