AP Calculus BC Score Calculator (2027)

The BC exam reports a second score, the AB subscore, built from the questions that cover AB-level topics (about 60% of the exam). Colleges that give credit for AB can use it even if your BC score is lower. This calculator estimates the BC score from your section points; the AB subscore follows the same 1 to 5 scale on the AB-level questions. This page is the BC Calculus AP score calculator; Calculus AB has its own page.

Historically a larger share of BC students earn a 5, around 40% in many years, because BC students have usually taken more math. The cutoff itself is not easier: on our table a 5 starts at about 60 of 100 composite points, a little lower than AB, and the questions cover more topics.

On our table a 5 starts at 60 of 100 composite points. With the official 50/50 weighting that is, for example, 30 of 42 multiple choice questions right plus about 30 of 54 free response points. Enter your own numbers and the goal box shows the exact gap.

Six questions at 9 points each: two in Part A with a graphing calculator and four in Part B without one. Rubric points reward setup, method, answer and justification, and the series question is usually the one that separates 4s from 5s.

A 3 starts at about 38.5 of 100 composite points on our table, which is roughly 38.5% of the available points. Because the sections are weighted, it depends on where you lose the points: with a strong free response section you can miss a good share of the 42 multiple choice questions. Enter your expected points and the goal box shows exactly what a 3 needs.

The section weights and point values come from the College Board's course and exam description and scoring guidelines, so the composite follows the official weighting for the points you enter. The 1 to 5 is an estimate: the College Board never publishes cutoffs, so our boundaries average published third party estimates, named under the result with the date we checked them. Your real score can differ by one step when you are close to a cutoff.

Yes, as long as your practice test has the same sections as the May 2027 exam described above. Enter your points from a released 2026 free response set or a full practice test and the composite is calculated the same way. The 1 to 5 uses our estimated 2027 cutoffs, and the 2026 score distribution on this page shows how real students did last May.

Many colleges give credit or placement for a 3, and selective colleges often ask for a 4 or 5 in this subject. The policy is set by each college, not by the College Board, so check the AP credit page of the colleges on your list before you decide which scores to send.
