The AP Calculus AB exam has two sections of equal weight, each split into a calculator and a no-calculator part. Section I gives you 105 minutes for 45 multiple-choice questions. Section II gives you 90 minutes for six free-response questions, each scored out of 9 points by AP readers.
Your raw points never go to colleges. The College Board combines your weighted section results into a composite score, then converts that composite to the 1-to-5 scale using a process called equating. Equating adjusts the cutoffs for each year's exam so that a 4 in 2026 represents the same level of mastery as a 4 in 2025, even if one version was slightly harder.
That is why no calculator — including this one — can tell you your exact score in advance. What it can do is map your practice raw scores onto cutoffs from publicly released past exams, which is precise enough to set a realistic target and to spot the section where extra points are cheapest for you.
Calc AB rubrics award points for the work, not just the answer: a correct setup with an arithmetic slip usually keeps most of the points, while a bare correct answer with no justification can lose them. Standard rubric language — showing the integral you evaluate, justifying with the relevant theorem — is worth learning verbatim.
