The Multiple-Choice Section (MCQ) of the AP Environmental Science exam is worth 60% of your total score. With 80 questions to answer in 90 minutes, speed, accuracy, and strategy are essential.
This RevisionDojo guide will give you the exact methods top scorers use to dominate the APES MCQs.
📌 APES MCQ Basics
- 80 questions
- 90 minutes total – ~1 minute per question
- 4 answer choices per question
- Covers Units 1–9 (ecosystems to global change)
- No penalty for wrong answers
🧠 Strategy 1 – Master Key Concepts
Multiple-choice questions often test:
- Cause and effect (e.g., “If biodiversity decreases, what happens to…”).
- Real-world applications (laws, policies, human impact).
- Data analysis (graphs, tables, diagrams).
Tip: Don’t just memorize — learn how to apply concepts in different scenarios.
🔍 Strategy 2 – Tackle Data-Based Questions First
- Identify x- and y-axes on graphs.
- Look for patterns, anomalies, and trends before reading the question.
- Pay attention to units and whether they’re per year, per capita, etc.
⏳ Strategy 3 – Manage Your Time
- Spend no more than 60 seconds per question on your first pass.
- Mark tricky questions and return later.
- Answer every question before time runs out — there’s no penalty for guessing.
🎯 Strategy 4 – Eliminate Wrong Answers
Ask yourself:
- Is it scientifically impossible?
- Does it contradict known environmental laws?
- Is it too extreme or absolute (“always,” “never”)?
If yes, eliminate it. Your odds improve with fewer choices.
📈 Strategy 5 – Look for Clues in the Question
- Sometimes one part of the question hints at another.
- Units, numbers, or key terms can point to the correct answer.
- Watch for “except” or “not” — these flip the meaning entirely.
💡 Practice Like It’s Test Day
- Use College Board released questions and reputable APES prep books.
- Time yourself with 90-minute practice blocks.
- Review why wrong answers are wrong — this builds test sense.
