How the AP Statistics score is calculated
Your two section scores are weighted: 50% multiple choice and 50% free response produce a weighted composite percentage. 40 MC (50%) + 6 FRQ incl. investigative task (50%). Curve from 2016 released exam. That composite is then compared to the estimated score bands — a 5 from about 70%, a 4 from 57% and a passing 3 from 44%.
Important: this is an estimate. College Board does not publish exact raw-to-scaled cutoffs; the curves are reverse-engineered from recently released exams and shift by ±2–3 points each year. For other subjects, open the AP score calculator hub.
