Frequently Asked Questions

What’s a good AP Biology score?

Scores of 3, 4, or 5 are considered good. A 3 is “qualified,” 4 is “well qualified,” and 5 is “extremely well qualified.” Most colleges accept scores of 3 or higher for credit.

How accurate is this calculator?

Our calculator uses official College Board scoring guidelines and historical data. While predictions are highly accurate, actual scores may vary slightly due to exam curve adjustments.

When are AP scores released?

AP scores are typically released in July through your College Board account. You can access them online using your username and password.

Can I retake the AP Biology exam?

Yes, you can retake AP exams. However, you’ll need to wait until the next administration year. Only your most recent score will be reported unless you specify otherwise.

Features:

1. User-Friendly Interface:
   • Clean, responsive design
   • Input validation
   • Clear section organization
2. Accurate Calculations:
   • Converts MCQ (60 questions) to a 50-point scale
   • Properly weights long (10pt) and short (4pt) FRQs
   • Combines scores for a 100-point composite
3. Visual Results:
   • Color-coded AP score (1-5)
   • Detailed score breakdown
   • Mobile-friendly layout

The AP Biology exam score is calculated based on two main sections:

1. Multiple-Choice (MCQ): 60 questions (50% of the exam score)
2. Free-Response (FRQ): 6 questions (50% of the exam score)
   • Q1 & 2: Long-response questions (8–10 pts each)
   • Q3–6: Short-response questions (4 pts each)

How to Estimate Your AP Biology Score:

1. Multiple-Choice Section (60 questions)
   • Raw Score = Number of correct answers (no penalty for wrong answers)
   • Convert to scaled score (out of 50).
2. Free-Response Section (6 questions, 50% of total score)
   • Each long FRQ (Q1 & 2) is worth ~13–15% of the FRQ score.
   • Each short FRQ (Q3–6) is worth ~5–7% of the FRQ score.
   • Total FRQ raw score (out of 50).
3. Composite Score (MCQ + FRQ)
   • Add the two scaled scores (out of 100).
4. Predicted AP Score (1–5):
   • 5: ~75–100
   • 4: ~60–74
   • 3: ~45–59
   • 2: ~30–44
   • 1: ~0–29

AP Bio Score Calculator

Step 1: Multiple-Choice Section (60 Questions)

• Enter the number of correct answers (out of 60):
  • Raw MCQ Score = [Your Correct Answers]

Step 2: Free-Response Section (6 Questions)

• Q1 & Q2 (Long FRQs) – Score out of 10 each:
  • Q1: [ /10 ]
  • Q2: [ /10 ]
• Q3–Q6 (Short FRQs) – Score out of 4 each:
  • Q3: [ /4 ]
  • Q4: [ /4 ]
  • Q5: [ /4 ]
  • Q6: [ /4 ]
• Total FRQ Raw Score = (Q1 + Q2) × 1.5 + (Q3 + Q4 + Q5 + Q6) × 1.25
  (This converts to a scaled score out of 50.)

Step 3: Calculate Composite Score

• Composite Score (out of 100) = (MCQ Raw Score × 0.83) + (FRQ Scaled Score)
  (Since MCQ is 50% of the exam, we scale it down.)

Step 4: Estimate AP Score (1–5)

Composite Score Range	AP Score
75–100	5
60–74	4
45–59	3
30–44	2
0–29	1

---

Example Calculation:

• MCQ: 45/60 correct → 45 × 0.83 ≈ 37.5
• FRQ:
  • Q1: 8/10, Q2: 7/10 → (8 + 7) × 1.5 = 22.5
  • Q3–Q6: 3, 3, 2, 4 → (3 + 3 + 2 + 4) × 1.25 = 15
  • Total FRQ Score = 22.5 + 15 = 37.5
• Composite Score = 37.5 (MCQ) + 37.5 (FRQ) = 75 → Predicted AP Score: 5
