AP CSP Score Calculator

This AP CSP score calculator estimates your AP Computer Science Principles score on the 1 to 5 scale. Unlike most AP exams, CSP has no traditional free-response section. Your score comes from 70 multiple-choice questions and the Create performance task, which is judged on a six-row rubric. Enter how many questions you got right and which rubric rows you expect to earn, and the tool shows your composite out of 100 and the AP score it most likely maps to.

The College Board weights the multiple choice at 70 percent and the Create task at 30 percent. Because the multiple choice has exactly 70 questions, the math is unusually clean: every correct answer is one composite point, and every Create rubric row is five. The rest of this page explains how the Create task is scored, walks through two examples, gives estimated cutoffs for 2024 to 2026 and the official 2026 results, and lays out a plan for a 5.

How to Use the AP CSP Score Calculator

• Multiple choice correct (0 to 70): include single-select and multiple-select questions. Each counts as one question.
• Create task, rows 1 to 6 (0 or 1 each): set a row to 1 if your work meets every criterion for that row, and 0 if it misses any of them. There is no half credit on a row.
• Curve year: switch between 2024, 2025 and 2026. Each year uses its own estimated cutoffs and the official score distribution. 2026 is the default.
• Target planner: pick a 3, 4 or 5 to see how far your composite is from that score, expressed as extra multiple-choice answers or extra Create rows.

Since the Video and Program Requirements rows are judged from work you have already submitted, you can usually be fairly confident about them before exam day. The four written-response rows are the ones to estimate conservatively.

AP Computer Science Principles Exam Format

AP CSP has a through-course part and an end-of-course exam. During the year you build a program for the Create performance task, using 9 hours of class time. On exam day you sit a 3-hour digital exam in Bluebook: 2 hours of multiple choice, then 1 hour of written responses about the program you made.

Section I: The Multiple-Choice Questions

Code in the multiple choice is written in the College Board's own pseudocode, in both text and block form, and an exam reference sheet explains how it works. There is no penalty for wrong answers. On the multiple-select questions you need both correct choices to earn credit.

Section II: How the Create Task Is Scored

You submit three things to the AP Digital Portfolio before the deadline: your program code, a short video of the program running, and a Personalized Project Reference (PPR) that shows key code segments. On exam day you answer two written-response questions while viewing your PPR. Written Response 2 has three parts. Trained AP readers then score the whole package on six rows, each worth one point, according to the College Board's 2025 scoring guidelines and its 2024 and 2025 scoring statistics.

The written-response prompts change each year and between exam versions, so rows 4 to 6 describe a category rather than a fixed question. In 2025, for example, one version of Written Response 2(a) asked students to identify the Boolean expression in a selection statement and a value that makes it true, while Written Response 2(b) asked them to describe a change that would introduce a logic error.

Calculators and Reference Material

Calculators are not allowed on AP CSP, except for students with an approved accommodation. You do not need one: questions about binary, data and algorithms are built to be done by hand. During the written responses you can view your own PPR, which is why it matters so much to choose clear, representative code segments for it.

AP CSP Composite Score Formula

Every Create row is worth five multiple-choice questions. That makes the rows the highest-value items on the exam, but also the riskiest, since each one is all or nothing. Losing a single row because one bullet of the criteria was missing costs as much as getting five more multiple-choice questions wrong.

Example 1: Strong All Around

A clean Create task plus 60 multiple-choice answers gives an eight-point cushion above the estimated 5 line. Even if this student lost one written-response row, the composite of 85 would still be a 5.

Example 2: A 3 With an Easy Path Up

This student needs 69 for a 4, eight more points. That could come from eight more correct multiple-choice answers, or from just two more Create rows (2 × 5 = 10, for a composite of 71). Rows 4 and 5, the algorithm and testing questions, are exactly the ones many students miss, so targeted practice on those two prompt types is the most efficient way to move up.

AP CSP Score Cutoffs (Estimated)

The College Board does not publish the composite needed for each AP CSP score. The ranges below are our estimates for 2026, which the calculator uses by default. They are based on the 70/30 weighting, the College Board's scoring statistics for the Create task and the official share of students at each score.

AP CSP results have been very steady, so the estimated cutoffs barely move. 2024 was the first year of the current Create format, with written responses answered on exam day, and students earned fewer Create points that year: the Set 1 average across the six rows was about 3.5, against about 4.1 in 2025. Lower Create scores with a near-identical distribution suggest a slightly lower bar in 2024, which is why its estimates sit a point or two below.

These cutoffs are estimates, not official figures. The College Board sets AP score boundaries each year to keep scores comparable across exams of different difficulty.

What Is a Good AP CSP Score?

A 3 passes and can earn credit or placement for an introductory computing course at many colleges. A 4 is a strong score that about a quarter of students reached in 2026. A 5 is rarer on CSP than on many AP exams: only 10 percent of 2026 test takers earned one, so it puts you in roughly the top tenth. If you plan to study computer science, check whether your college treats CSP as credit toward the major or only as an elective.

The 2026 percentages above are the whole numbers the College Board posted. The most recent published mean is 2.87, from 2025, when 175,174 students took the exam.

AP CSP Score Distribution and Trends

The pass rate has stayed between about 62 and 67 percent every year since 2021, and the mean has drifted only from 2.99 to 2.87. The most common score is a 3, which roughly three in ten students earn. The share of 5s has eased slightly from 12.4 percent in 2021 to 10 percent in 2026, while the exam has grown to more than 175,000 students.

Almost everyone earns the Video row, and most students earn Program Requirements and Written Response 1. The three parts of Written Response 2 are where points disappear. In 2024 fewer than a third of students earned the 2(b) or 2(c) point, and in 2025 fewer than half earned 2(a). Those rows decide whether a student lands a 3 or a 4.

Multiple-Choice Score Needed for a 3, 4 or 5

Because the Create task has only seven possible outcomes (0 to 6 rows), the clearest way to plan is to ask how many multiple-choice answers you need for each Create result. The figures below use the estimated 2026 curve.

With a full Create score, a 5 needs about three quarters of the multiple choice. Drop to three rows and a 5 needs 67 of 70, which almost nobody manages. In short, a polished Create task gives you room to miss questions, and a weak one forces near-perfection on the multiple choice.

How to Get a 5 on AP Computer Science Principles

Algorithms and Programming is the heaviest of the five big ideas, but the conceptual topics together make up most of the multiple choice, so a programming-only study plan leaves points on the table.

• Lock in the two rows decided before exam day. Make sure your video clearly shows input, the program doing its job and the resulting output, and check your code for every program requirement: a procedure you wrote, a call to it, a list that actually matters to the program, selection and iteration.
• Build your PPR for the questions you will face. Include a procedure with a parameter that affects what it does, a call to it, the code that stores data in your list and the code that uses that list. You will look at these segments while you write, so pick ones you can explain line by line.
• Practice Written Response 2 with released prompts. Rehearse tracing your own selection statements with sample values, describing how an edit would create a logic error, and explaining how your list manages complexity in your program.
• Answer the exact question. The rubric says responses are judged only on what they state, and every bullet must be met. A response that explains a different code segment, or skips one bullet, earns zero for the row.
• Master the pseudocode on the exam reference sheet, especially list indexes starting at 1, REPEAT UNTIL loops and procedure returns. Tracing short code by hand is the most common multiple-choice skill.
• Do not neglect Big Idea 5. Questions on the impacts of computing, bias, privacy, the digital divide and crowdsourcing make up about a quarter of the exam and reward careful reading more than memorization.
• Review binary conversion, overflow and rounding errors, lossless versus lossy compression, the internet's packet routing and fault tolerance, and parallel versus sequential speedup. These topics repeat in almost every practice set.
• Take timed 70-question practice sets in two hours, then enter your score and expected Create rows above to see which side of a cutoff you are on.

How Accurate Is This AP CSP Score Calculator?

The composite formula is exact: 70 percent for 70 questions and 30 percent for six one-point rows are official. What remains uncertain is where the 1 to 5 lines fall, since the College Board sets them each year and does not publish them. Our estimates are drawn from the published distributions and Create scoring statistics, so treat any composite within about two points of a cutoff as a coin flip.

Your guess about the written-response rows is the other big variable. A single row is worth five points, so being optimistic about two rows can inflate a prediction by ten. If you are unsure whether a response met every bullet, set that row to 0 and see whether your predicted score changes.

AP CSP Deadlines, Exam Date and Score Release

For the 2027 exam, the College Board lists two dates. Your program code, video and PPR must be submitted as final in the AP Digital Portfolio by Friday, April 30, 2027, at 11:59 p.m. ET, and work that is not submitted as final cannot be scored. The end-of-course exam, including the written responses, is scheduled for Friday, May 14, 2027, in the morning session (Session 1). Scores usually appear in early July. Confirm all dates with your AP coordinator and on the official College Board schedule.
