How Is the AP Biology Score Calculated?
Calculating your AP Biology score involves a two-step process. First, your raw scores from the Multiple Choice (MCQ) and Free Response (FRQ) sections are tallied. Then, these raw scores are weighted to create a Composite Score (usually out of 100 or 120), which is finally mapped to the 1-5 scale.
Multiple Choice (MCQ)
- Questions60
- Time1hr 30min
- Weight50%
Free Response (FRQ)
- Questions6 (2 Long, 4 Short)
