How the AP Stats Score Calculator works
AP Statistics weights the 40 question multiple choice section at 50% of the exam and the free response section at 50%. The free response section has six questions scored 0 to 4 each (five short plus the investigative task), for 24 points total. The investigative task counts extra within the section. The weighted composite maps to a 1 to 5 scale with cutoffs that typically sit near 65% for a 5 and 40% for a 3.
Composite = MC/40 × 50 + FRQ/24 × 50
Cutoffs are set fresh by the College Board after every administration, so treat the output as a well-informed estimate rather than a guarantee, especially within a few points of a boundary.
Frequently asked questions
What score do I need for a 5 on AP Stats?
A weighted composite around 65% or higher typically lands a 5, though the College Board sets exact cutoffs after each administration. Strong performance on both sections is the safest route since the multiple choice carries 50% of the weight.
How is the AP Stats exam weighted?
The multiple choice section (40 questions) counts for 50% of the composite and the free response section counts for 50%. The free response section has six questions scored 0 to 4 each (five short plus the investigative task), for 24 points total. The investigative task counts extra within the section.
What is the AP Stats investigative task?
Question 6 is a longer multi-part problem that stretches course concepts into a new situation. It officially counts for a larger share of the FRQ section, so budget 25 to 30 minutes for it.
Are these cutoffs official?
No. The College Board sets cutoffs after each administration and does not publish them in advance. These estimates come from released exams and typical year-to-year ranges, so treat borderline composites with caution.
