How Is the AP Environmental Science Exam Scored?
The AP Environmental Science (APES) exam is divided into two main sections, weighted to produce a final composite score. Understanding this weighting is crucial for strategic studying.
1. Multiple Choice Questions (MCQ)
This section consists of 80 questions that you must answer in 90 minutes. It accounts for 60% of your total exam score. Unlike some older AP exams, there is no penalty for guessing; your score is based solely on the number of questions answered correctly.
2. Free Response Questions (FRQ)
This section consists of 3 questions to be answered in 70 minutes. It accounts for 40% of your total exam score. Each question is scored on a scale of 0 to 10 points.
- Question 1: Design an investigation.
- Question 2: Analyze an environmental problem and propose a solution.
- Question 3: Analyze an environmental problem and propose a solution doing calculations.
Calculating the Composite Score
To convert your raw scores into the final 1-5 AP scale, a composite score is calculated out of approximately 150 points:
- MCQ Calculation: (Number Correct / 80) × 90 points. (Multiplier: ~1.125)
- FRQ Calculation: (Total FRQ Points / 30) × 60 points. (Multiplier: ~2.0)
APES Score Distributions and Cutoffs
While the College Board adjusts the curve slightly every year based on exam difficulty, the following table represents typical composite score ranges required for each AP score:
| AP Score | Composite Range (Est.) | Rating | College Credit? |
|---|---|---|---|
| 5 | 114 – 150 | Extremely Well Qualified | Yes |
| 4 | 93 – 113 | Well Qualified | Yes |
| 3 | 75 – 92 | Qualified | Usually |
| 2 | 58 – 74 | Possibly Qualified | Rarely |
| 1 | 0 – 57 | No Recommendation | No |
Strategies to Improve Your Score
To maximize your chances of scoring a 4 or 5:
- Master the Math: Question 3 often involves calculations. Practice dimensional analysis and scientific notation without a calculator, as mental math speed helps.
- Vocabulary is Key: APES is vocabulary-heavy. Ensure you know specific terms like "eutrophication," "bioaccumulation," and "anthropogenic."
- Pacing: With 80 MCQs in 90 minutes, you have just over a minute per question. Don't get stuck on difficult questions early on.
