How AP scores are calculated

Every AP exam with a written exam has two parts. Multiple choice is scored by machine with no penalty for wrong answers. Free-response answers are scored by AP readers against a published rubric. Each section is converted to a weighted composite, and College Board sets the composite ranges for 1 to 5 each year after scoring — those ranges aren't published, which is why every AP calculator, ours included, uses estimates.

Questions

How are AP scores calculated?

Your multiple-choice and free-response points are each converted to a share of their section, multiplied by the section's weight, and added into a composite score. College Board then sets cutoffs that turn composite ranges into scores from 1 to 5.

What AP score do colleges accept for credit?

Most colleges give credit for a 3 or higher, but many selective universities require a 4 or 5, and some only use AP scores for placement. Check each college's AP credit policy page.

Is a 3 a passing AP score?

College Board calls a 3 'qualified', and it's the usual minimum for college credit. A 4 is 'well qualified' and a 5 'extremely well qualified'.

How accurate is an AP score calculator?

It's as accurate as your point estimates and the curve. Free-response scores are the biggest unknown; score your practice answers with the official rubric for the most realistic prediction.
