Ap Bio Score Breakdown: Raw Points to Composite Score Conversion Chart
By Sophia Al-Mansoor
Q1: What raw composite score guarantees a 5 on the AP Biology exam?
A1: An estimated composite score of 93 out of 120 (77.5%) has reliably crossed the threshold for a 5 across all recent College Board scoring curves. In years with unusually difficult prompts, the cutoff has dropped as low as 89 or 90 points.
Q2: How does the free-response weighting work if individual FRQs change in point value?
A2: The six FRQ prompts collectively sum to 40 raw points, consisting of two long prompts (typically 8 to 10 points each) and four short prompts (4 points each). Once an official grader records your raw total out of 40, that number is multiplied by 1.5 to scale Section 2 to 60 composite points.
Q3: Are points deducted for incorrect guesses on the multiple-choice section?
A3: No. The College Board scores Section 1 on raw correct responses only. Unanswered questions and incorrect choices receive zero points, meaning students should record an answer for all 60 questions before time expires.
