AP Calculus AB Score


The multiple choice component of the exam is scored by computer, while the free response sections are scored by trained AP readers. The scores on various components are weighted and combined into a raw Composite Score. The Collegeboard then decides on the grade cutoffs for that year's exam, which determine how the Composite Scores are converted into the final grades, the overall goal being for the grades to reflect an absolute scale of performance, comparable from year to year.
This calculator reflects the 2008 AP Calculus AB grade cutoffs.

Beginning with the May 2011 AP Calculus AB exam, the method for scoring the multiple-choice section has changed. The total scores on the multiple-choice section are now based on the number of questions answered correctly and points are no longer deducted for incorrect answers. As always, no points are awarded for unanswered questions.

The table below shows the conversion chart between the composite score and the final AP score for the AP Calculus AB 2008 test:

Composite Score RangeAP Calculus AB Score
68 - 1085
52 - 674
39 - 513
27 - 382
