Frequently Asked Questions
Multiple-choice correct answers and free-response rubric points are each multiplied by a section weight, then summed into a composite score. That composite is compared against cutoff bands to determine the final 1–5 AP score. Section structures come from College Board's published exam format; the specific weight multipliers and cutoffs are this site's modeled estimate, not an official published formula.
No. College Board eliminated guess penalties across all AP exams. You earn points only for correct answers, and blank or incorrect answers both receive 0 points — so there's no reason to leave a question unanswered.
A score of 3, 4, or 5 is generally considered passing and eligible for college credit or advanced placement, though this varies by university and some selective schools require a 4 or 5. Check your target school's AP credit policy directly.
