AP Calculus AB 2026–27: Calculator Rules Change Four Times, and 68.3% Is No-Calculator
AP Calculus AB is unusual among AP exams in that calculator access changes four separate times within one sitting. Two parts forbid a graphing calculator and two require one, and the no-calculator portions carry the larger share of the score — 68.3% of the total between them. That structure should shape how you practise. Most candidates rehearse with a calculator to hand because that is how homework works, which means they train the 31.7% and neglect the two-thirds. This page sets out each part, its calculator rule and its exact weight, what the exam costs including the fees people forget, and the May 10, 2027 date.
AP Calculus AB runs 3 hours 10 minutes. Section I is 42 multiple-choice questions in 1 hour 40 minutes: Part A is 29 questions with no graphing calculator (35% of the total score) and Part B is 13 questions where a graphing calculator is required for some (15%). Section II is 6 free-response questions in 1 hour 30 minutes: Part A is 2 calculator-required problems (16.7%) and Part B is 4 no-calculator problems (33.3%). It is a hybrid digital exam — questions appear in Bluebook, but free-response answers are handwritten in paper booklets.
