Ap Bio Calculator

Preparing for the AP Biology exam can be stressful, especially when you’re unsure how your practice scores translate into the official 1–5 scale. The AP Biology Score Calculator is a free online tool designed to help students predict their potential AP scores based on raw performance in both the Multiple-Choice Questions (MCQs) and the Free Response Questions (FRQs).

This calculator uses official scoring curves released by the College Board from previous years (2011–2019) to provide accurate estimates. By entering your correct answers and average FRQ scores, you’ll get an estimated composite score and a predicted AP score (1–5 scale).

This tool is perfect for:

• Students preparing for the AP Biology exam
• Teachers helping students understand score ranges
• Test prep tutors creating study plans
• Anyone looking for a quick and reliable score prediction

5. Select the Scoring Curve Year
   • Choose from available years (2011, 2012, 2013, or 2019).
   • Each year has slightly different cutoffs for AP scores.
6. Click “Calculate”
   • The tool will process your inputs, simulate the scoring curve, and give you:
     • MCQ Raw Score
     • FRQ Raw Score
     • Composite Score (0–124)
     • Predicted AP Score (1–5)
7. Review Your Results
   • Use the provided AP scoring scale table to compare composite scores across years.
   • Copy or share your results with a single click.
8. Reset if Needed
   • Start over anytime by pressing the “Reset” button.

Example: Predicting an AP Biology Score

Let’s walk through a real example:

• MCQ Correct: 45/60
• Long FRQs Attempted: 2
• Short FRQs Attempted: 4
• Average Long FRQ Score: 7.5
• Average Short FRQ Score: 3
• Curve Year Selected: 2019

Step 1 – MCQ Calculation
45 × 1.03 = 46.35 (out of max 62)

Step 2 – FRQ Calculation
(2 × 7.5) + (4 × 3) = 15 + 12 = 27 raw
Scaled to 62 = (27 ÷ 36) × 62 = 46.5

Step 3 – Composite Score
46.35 + 46.5 = 92.85 → Rounded = 93

Step 4 – Final AP Score (2019 Curve)
Composite 93 = AP Score 5 🎉

This student’s predicted score is a 5, which is the highest possible AP grade.
