- Method updated Nov 13, 2026Our model used to assume students score the same share of the multiple-choice points as of the free-response points. On all 7 released College Board charts we can check against that year’s free-response statistics, the multiple-choice share was higher (51% to 72% of points), so the model now uses the share measured there. Our AP® Calculus AB score lines rose by 5.2 points; every subject’s lines rose, most by about 4 to 5.5 points (all 4.1 to 9.2).our method notes, Nov 13, 2026

- How sure this isWe check our method against College Board’s released 2012-13 scoring charts, which exist for 9 subjects. For 7 of them College Board’s free-response statistics from the same year also exist, so the whole method can be tested: predicting each chart from the others, our 28 score lines missed by a median of 2.5, a mean of 3.7 and at most 9.9 composite points. Checked against College Board’s released 2012 AP® Calculus AB chart, our lines missed by 2.6 to 9.9 points. By line: 9.9, 8.1, 5.0 and 2.6 points at the 2, 3, 4 and 5 lines, so we show 10 points around the 2 line, 8.5 around the 3, 5.5 around the 4 and 8 around the 5.from our method notes, Nov 13, 2026
Assumptions: College Board rounds the two free-response parts to 16.7% and 33.3%; we use exact thirds.

Assumptions: College Board's Calculus BC page gives multiple choice as 50% without the Part A / Part B split, so we use the Calculus AB split (35% and 15%). That is our assumption. College Board rounds the two free-response parts to 16.7% and 33.3%; we use exact thirds.
Your composite is each part’s raw points times its weight, added up to 100. Score lines move every year because each exam version is equated, so near a line we show a range instead of one score.
AP® Calculus score questions

Should I pick AB or BC?
Pick the exam you are registered for. Both have 42 multiple-choice questions and 6 free-response questions in May 2027, but each has its own students and its own score lines, so the same points can land on a different score.
How many students scored a 5 in 2026?
In AP® Calculus AB, 20% scored a 5; in AP® Calculus BC, 46% (College Board’s published 2026 shares, whole numbers so far).
Can I save my practice test result?
Yes. Copy link gives you a link that holds your points and your AB or BC choice, so it opens the same result. Nothing is stored on our side.
