AP Score Calculator
Estimate an AP score of 1–5 from raw points with College Board practice-exam charts for Calculus AB and BC, Biology, Psychology, and Macroeconomics.
Estimated AP score

Cut points are the College Board 2012 AP Calculus AB Practice Exam scoring worksheet: composite out of 108, with multiple choice scaled to 54 and free response worth 54. That form multiplied 45 multiple-choice questions by 1.2000. The May 2027 exam has 42 multiple-choice questions, still 50% of the score, so each correct answer is multiplied by 54/42. College Board sets the operational curve after the exam and has not published a May 2027 chart.
| AP score | Composite |
|---|---|
| 5 | 67–108 |
| 4 | 54–66 |
| 3 | 41–53 |
| 2 | 33–40 |
| 1 | 0–32 |

Pick Calculus AB, Calculus BC, Biology, Psychology, or Macroeconomics, enter the section scores, and read an estimated AP score of 1 to 5. The cut points come from College Board practice-exam scoring worksheets, 2012 for calculus, psychology, and macroeconomics, and 2013 for biology, scaled to the section weights those exams use now. College Board sets the real curve after the May exam. AP English Language, AP US History, AP Chemistry, AP English Literature, AP World History, AP Physics 1, and AP US Government are described below and left off the menu, because no verified conversion chart turned up for their current sections.
Five exams, one set of boxes
The Exam menu is the whole switch. Calculus AB, Calculus BC, Biology, Psychology, and Macroeconomics each bring their own boxes, because the sections are not the same test. Calculus AB asks for multiple-choice questions correct out of 42 and six free-response scores out of 9. Biology asks for 60 multiple-choice questions and six free-response scores: two long questions, each out of the 8, 9, or 10 points its rubric uses and scaled to 9, and four short ones out of 4. Psychology asks for 75 multiple-choice questions, an Article Analysis Question out of 7, and an Evidence-Based Question out of 7. Macroeconomics asks for 60 multiple-choice questions, one long free-response out of 10, and two short ones out of 5. Changing the exam clears the boxes.
There is no calculate button. The estimated AP score updates when every box holds a number inside its range, and it stays a dash until then. A number past the maximum, or a negative, turns that box's hint red and keeps the dash. The working line under the score shows each entry times its weight, which is how the composite is built.
The charts are printed College Board worksheets
College Board does not publish the raw-score cutoffs for the exam you sit in May. It does print a conversion chart on some practice-exam scoring worksheets, and those are the ranges in the table under the result. Calculus AB and Calculus BC use the 2012 practice exams. On AB, a rounded composite of 67 to 108 was a 5, 54 to 66 a 4, and 41 to 53 a 3, out of 108. BC's 2012 chart starts a 5 at 68. Biology uses the 2013 practice exam, out of 120, where 93 to 120 was a 5 and 54 to 74 was a 3. Psychology uses the 2012 practice exam, out of 150, where 112 to 150 was a 5 and 79 to 93 was a 3. Macroeconomics uses the 2012 practice exam, out of 90, where 71 to 90 was a 5 and 51 to 58 was a 3.
The question counts on those old forms are not always the question counts on the current exam, so the weights scale today's sections onto the worksheet's section totals. The note under the score says which year, what the form looked like, and what changed. College Board sets the real curve after the exam. A composite that lands on a boundary can come back one score to either side once that year's chart is set.
AP Lang, APUSH, and the exams left off the menu
AP English Language is 45 multiple-choice questions, 45% of the score, and three essays, synthesis, rhetorical analysis, and argument, 55% together. AP English Literature is 55 multiple-choice questions at 45% and three essays at 55%: a poem, a prose passage, and an open literary argument. AP Chemistry is 60 multiple-choice questions at 50% and seven free-response questions at 50%, three long questions at 10 points and four short ones at 4. AP Physics 1, for the May 2027 exam, is 42 multiple-choice questions at 50% and four free-response questions at 50%: mathematical routines, translation between representations, experimental design, and qualitative/quantitative translation. AP US Government is 55 multiple-choice questions at 50% and four free-response questions at 50%: concept application, quantitative analysis, a SCOTUS comparison, and an argument essay.
AP US History is 55 multiple-choice questions at 40%, three short-answer questions at 20%, a document-based question at 25%, and a long essay at 15%. AP World History: Modern is built the same way, with a multiple-choice section, short answers, a document-based question, and a long essay. Those are the section weights College Board publishes. A 2013 World History practice exam does include a conversion chart, and that exam was 70 multiple-choice questions plus three essays, which is a different test from the current one. No College Board chart turned up for the current section weights of Lang, Literature, Chemistry, Physics 1, Government, US History, or World History, so those exams are not on the menu. Guessing a cutoff for them would just be a made-up number.
Reading the score and the composite
The large number is the estimated AP score from 5 down to 1, with the College Board wording beside it: extremely well qualified, very well qualified, qualified, possibly qualified, or no recommendation. The composite underneath is the weighted total rounded to the nearest whole number, which is the rounding instruction on the worksheets. If the unrounded total is not already a whole number, it is shown in parentheses so you can see a 66.6 become a 67.
The table lists every range for the exam you picked. A dash means at least one box is empty or outside its range. Fill the blanks with zeros if you want to see the floor.

Frequently Asked Questions
Is this an AP Lang score calculator?
The menu does not score AP English Language. That exam is 45 multiple-choice questions worth 45% and three essays worth 55%, and College Board has not published a raw-score chart for that layout that this page could verify. The same goes for AP English Literature, AP US History, AP World History: Modern, AP Chemistry, AP Physics 1, and AP US Government.
Which exams can I score?
AP Calculus AB, AP Calculus BC, AP Biology, AP Psychology, and AP Macroeconomics. Each one uses a conversion chart printed on a College Board practice-exam scoring worksheet, named under the result with the exam year.
Does College Board set the curve after the exam?
Yes. The ranges here are from a practice-exam worksheet for the year printed on the chart. The operational exam gets its own cut points after students have taken it, so a score on the boundary is an estimate.
Why does the composite get rounded?
The worksheets say to round the composite to the nearest whole number, then read the chart. A total of 66.5 becomes 67.
Does a 5 take the same share of points on every exam?
No. On these worksheets a 5 started at about 62% of the composite on Calculus AB (67 of 108) and 63% on Calculus BC (68 of 108), but about 75% on Psychology (112 of 150), 78% on Biology (93 of 120), and 79% on Macroeconomics (71 of 90). A 3 ranged from 38% on Calculus AB to 57% on Macroeconomics. Each exam's page lists its own cut points.
Why do some free-response points count more than one?
The worksheet scales each section to a fixed total. On Psychology, a 7-point free-response question is multiplied by 3.5714, the factor printed on the 2012 sheet. On Biology, free-response points are multiplied by 60/34 so six current questions fill the 60-point section on the 2013 sheet.
Is it free, and does it save what I type?
It is free, with no account. The arithmetic stays in your browser, and the entries disappear when you leave the page.
