How Long Is the AP CSP Exam?

The quick answer: the AP CSP end-of-course exam is 2 hours (120 minutes) of testing time — 70 multiple-choice questions plus two written-response questions about your Create task — taken in May. That makes it one of the shorter AP exams on test day. But AP CSP is unusual: it also includes the Create performance task, a program you build during the course over at least 9 hours of in-class time, submitted before the exam (by a late-April deadline, ~April 30). So there are two different “how long” answers: the timed exam is 2 hours, but the full assessment also includes those 9+ hours of through-course project work. On the exam, you get about 1.7 minutes per multiple-choice question, plus time for the written responses. As with all APs, total time at the testing center exceeds 2 hours (check-in, Bluebook setup, instructions). Here’s the full breakdown of both components.

The two “how long” answers

CSP is the rare AP where “how long is the exam” has two legitimate answers. Understanding both prevents confusion.

Unlike almost every other AP exam, AP CSP has two distinct time components, which is why “how long is the exam” can be answered two ways. The first answer — and the one most people mean — is the end-of-course exam: 2 hours (120 minutes), taken on a test day in May, consisting of 70 multiple-choice questions plus two written-response questions about your Create task. The second answer is the Create performance task: at least 9 hours of in-class time, spread across the course, during which you build your program, record a video, and create your Personalized Project Reference — all submitted before the exam. These two are separate: the 9+ hours of project work happens earlier in the year and is not part of the 2-hour exam sitting. So the precise answer is: the timed exam is 2 hours, but the complete AP CSP assessment also involves 9+ hours of through-course project work. This split matters for planning — you can’t just study for a test at the end; you also have to budget project time across the course. The rest of this guide covers both. For how the two components are scored, see the exam format guide.

The 2-hour end-of-course exam

Let’s focus on the test-day exam first, since that’s the timed portion. Two hours, seventy questions, plus written responses.

The end-of-course exam is the timed test you sit in May, and it runs 2 hours (120 minutes). In that time, you complete two things: the 70 multiple-choice questions (drawing on all five Big Ideas, using AP pseudocode) and the two written-response questions (four prompts total) about the code in your Personalized Project Reference. The entire exam is fully digital, taken in the Bluebook app, and everything is submitted automatically at the end. The 2-hour length makes this a relatively short AP exam on test day — many AP exams run 3 hours or more. It’s worth being clear about what’s included in the 2 hours: both the multiple-choice questions and the written responses about your Create task are answered within this single timed window. So on exam day, you’ll want to manage your time between the multiple-choice questions and the written responses — though since the written responses are about your own project (which you already understand deeply if you’ve prepared), they can go relatively efficiently, leaving most of your time for the multiple-choice section. The key point: the test-day exam is a focused 2 hours, all digital, combining the multiple choice and the Create-task written responses. For the detailed content breakdown, see the format guide.

How much time you get per question

Within the 2-hour exam, here’s how the time breaks down per question. A little over a minute and a half each.

On the multiple-choice section, you have 120 minutes for 70 questions — about 1.7 minutes (roughly 1 minute 40 seconds) per question — though you’ll also reserve some of that time for the written responses. This is a reasonable pace: some questions are quick (a definition, a straightforward concept about data or the Internet), while others take longer — especially tracing through a segment of pseudocode to predict its output, or analyzing a scenario about the impact of computing. The 1.7-minute average means banking time on the quick questions to spend on the code-tracing and analysis questions that need more thought. For the two written-response questions about your Create task, you’ll want to budget enough time to answer all four prompts clearly — but because they’re about your own code (which you know well if you’ve prepared), they can go relatively quickly. Good pacing on CSP means: move efficiently through the multiple choice, flag and return to hard questions rather than getting stuck, answer every multiple-choice question (no penalty for wrong answers), and leave sufficient time for the written responses. Since the exam is digital, the Bluebook app shows your time remaining, so you can monitor your pace. The table summarizes the timing.

The 9+ hours of Create task time

The other time component happens during the course, not on test day. This is where much of the work lives.

The second time component is the Create performance task, for which you’re given at least 9 hours of in-class time to build your program. This time is spread across the course — typically the second half of the year — not concentrated on a single day. During these 9+ hours (and often additional time outside class), you develop your computer program, test and refine it, record a video of it running, and create your Personalized Project Reference (PPR). This is substantial, hands-on work: you’re designing and coding an actual program of your choice, which takes real time and effort. The 9 hours is a minimum — the College Board requires at least that much dedicated class time, and many students use more to build a solid project. Crucially, this Create task time is part of the assessment (it’s 30% of your score), even though it doesn’t happen on exam day. That’s why, when thinking about how long AP CSP takes, it’s incomplete to say just “2 hours” — the full assessment includes those 9+ hours of project work earlier in the year. The practical implication: plan for steady Create task work across the course, not just end-of-year exam study. This is a defining feature of CSP’s timing. For how to approach the project, see the practice guide.

When the Create task is due

The Create task has a firm deadline well before the exam, and missing it is costly. Late April, typically around the 30th.

The Create performance task must be submitted as final through the AP Digital Portfolio by a deadline in late April — typically around April 30 — before the May end-of-course exam. By that deadline, you need to have completed your program, recorded your video, and finalized your Personalized Project Reference, then submitted everything. The exact date is set by the College Board each year, so confirm the current year’s deadline on the official AP CSP pages or with your teacher. This deadline is critical: missing it means losing the 30% of your score that the Create task represents — a severe penalty. Because you’re given at least 9 hours of in-class time, most students work on the task steadily across the second half of the course and finalize it well before the late-April deadline rather than rushing at the end. The key timing takeaway: the Create task deadline (late April) comes before the exam (May), so your CSP year has two distinct deadlines — submit the project in late April, then sit the exam in May. Your AP coordinator and teacher will remind you of the exact date, but plan ahead. For the full exam-day picture, see the format guide.

Total time at the testing center on exam day

Like all APs, the 2-hour exam means a longer day at the test center. Budget extra time on site.

As with every AP exam, the 2 hours of testing is not the whole exam-day experience — the total time at the testing center is longer. Several things add to the day: arrival and check-in, getting seated and verifying your identity, the Bluebook digital setup (CSP’s exam is fully digital, so you’ll log in and get the app ready), listening to the proctor’s instructions, and filling in any required information. None of this counts toward your 2-hour testing time, but it adds to how long you’re at the test site. Plan to be at the testing center for longer than 2 hours — often closer to 3 hours once setup and instructions are included — even though the actual timed exam is 2 hours. The practical advice: arrive on time (or early), and don’t schedule anything tight right after. Because CSP’s exam is shorter than many (2 hours of testing vs. 3+ for some), the exam day itself is relatively manageable — the bigger time commitment for CSP is the through-course Create task, not the test day. Knowing this helps you plan exam day realistically. Your proctor will guide you through the timing.

How AP CSP’s length compares to other exams

Whether CSP is “short” depends entirely on which time component you count. Short test, big project.

Comparing AP CSP’s length to other AP exams gives two different pictures, depending on what you count. On test day alone, AP CSP is one of the shorter AP exams: its 2-hour end-of-course exam is well under the 3-plus hours of many APs (like AP Calculus, AP Biology, or AP US History). So if you’re comparing test-day sitting time, CSP is short. But if you count the whole assessment, the picture changes: AP CSP also requires the Create performance task, which takes at least 9 hours of in-class time to build. Adding that in, the total time invested in the AP CSP assessment is substantial — arguably comparable to or more than many exams once the project is included. So the honest comparison is: CSP trades some end-of-year test length for a large through-course project. This is a different distribution of effort than most APs, where nearly all the assessment happens on one test day. For students, this means CSP’s time demand is spread across the year (project + exam) rather than concentrated at the end. Whether that makes CSP feel “shorter” or “longer” depends on how you prefer to work. For where CSP sits among all exams by test-day length, see the guide to how long AP exams are.

Pacing strategy for exam day

Knowing the timing, here’s how to manage the 2-hour exam. A few habits keep you on track.

These habits keep the 2-hour exam comfortably manageable. The key insight is that CSP’s test-day timing is not tight — 2 hours for 70 multiple-choice questions plus written responses about a project you already know is reasonable, especially since the written responses go quickly if you’ve prepared your Create task. Because the exam is on the shorter side, stamina isn’t the issue — the challenge is steady pacing and reserving time for the written responses. The bigger time-management task for CSP is the through-course Create task, which is why planning your project time across the year matters more than exam-day pacing. Practicing under timed conditions makes the exam pace feel natural; the practice guide shows how, and the AP score calculator helps you set your target.
