AP Environmental Science (APES) covers a broad range of interconnected topics—from ecosystems and biodiversity to energy resources and global change. Without an effective note organization system, reviewing before the exam can feel overwhelming.
In this RevisionDojo guide, we’ll walk you through proven strategies to organize APES notes so you can quickly recall key concepts, identify weak areas, and save valuable time in the weeks leading up to your test.
Why Note Organization Matters for APES
- Speeds Up Review – You’ll quickly find what you need instead of scanning through messy pages.
- Improves Retention – Structured notes help your brain categorize and store information effectively.
- Supports APES Exam Structure – Well-organized notes mirror the College Board’s unit breakdown, making it easier to target specific question types.
Step 1 – Organize Notes by APES Units
The College Board divides APES into 9 units, each with a specific percentage weight on the exam. Structure your notebook or digital folder like this:
- Unit 1: Ecosystems
- Unit 2: 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
Within each unit, break down into subtopics (e.g., for Unit 1: biomes, food webs, productivity, ecological succession).
