Section Breakdown

How It Works

APES (AP Environmental Science) has two parts: Section I (Multiple Choice) with about 80 questions, and Section II (Free Response) with 3 prompts, typically 10 points each, totaling 30 points by default.

Default weights are MCQ 60%, FRQ 40%. You can adjust weights, FRQ totals, and the scoring curve in Advanced Settings.

We compute a weighted raw percentage and map it to a 1–5 estimate using adjustable score bands. The exact AP curve varies each year based on exam difficulty and overall student performance.

Inputs Explained

  • MCQ Correct and Total: Enter the number of multiple choice questions you answered correctly out of 80 (default). You can change the total if you used a different practice test.
  • FRQs 1-3: Enter rubric points (0-10 each by default) for the three free-response questions. These typically cover data analysis, environmental problems and solutions, and policy/management scenarios.
  • Advanced Settings: Adjust section weights (must sum to 100%), edit FRQ totals if your rubric differs, and customize score band thresholds to match a specific curve.

Example Calculation

Let's walk through a sample calculation:

  • MCQ: 54 out of 80 → 54 ÷ 80 = 67.5%
  • FRQs: 7 + 8 + 6 = 21 out of 30 → 21 ÷ 30 = 70.0%

Using the default weights (MCQ 60%, FRQ 40%), the weighted raw percentage is:

(0.675 × 0.60) + (0.700 × 0.40) = 0.405 + 0.280 = 0.685 → 68.5%

With the default curve, 68.5% falls into the 60-74% range, yielding an estimated score of 3.

Tips & Notes

  • Curves Change Yearly: College Board adjusts the curve annually based on overall performance. Treat this calculator as a study guide, not a prediction of your actual score.
  • FRQ Strategy: Show units in calculations, set up proportions and dimensional analysis clearly, and tie environmental impacts to specific causes and policy solutions. Small rubric gains can significantly impact your overall estimate.
  • Master Key Themes: Practice common topics—sustainability, energy resources (renewable vs. non-renewable), population dynamics, pollution types and control, ecosystem services, and Earth systems (water, carbon, nitrogen cycles).
  • Dimensional Analysis: Be fluent with unit conversions and using conversion factors. Many FRQ questions require calculations with proper units.
  • Data Interpretation: Practice reading graphs, charts, and tables. Be able to identify trends, calculate rates of change, and make predictions based on data.

Frequently Asked Questions

This calculator provides an approximation using typical weights and a banded curve. Real AP scoring varies yearly depending on exam difficulty and student performance. Use this tool for practice and study planning only.

Yes. Open the Advanced Settings panel to edit section weights (MCQ and FRQ), FRQ totals, and score band thresholds. Click "Reset to defaults" anytime to restore built-in settings.

You can edit the MCQ total field and FRQ totals in Advanced Settings so your percentages accurately reflect your test format. This allows the calculator to work with custom practice tests.
