The AP CSP exam has two distinct parts: a 70-question multiple-choice section and a Create Performance Task you build before exam day. Knowing exactly how each part is scored and what each prompt type expects is the fastest way to raise your score.
Use this guide to understand the exam format, plan your Create task timeline, and focus your MCQ review on the question types that trip students up most.
AP CSP is structured differently from most AP exams because a significant portion of your score comes from work you do before exam day. The Create Performance Task is submitted through the AP Digital Portfolio by the end-of-April deadline, and then you answer written-response prompts about your own project during the May exam. The MCQ section covers all the big ideas from the course and is the single largest factor in your final score.
AP CSP is generally considered one of the more approachable AP exams. It does not require prior coding experience, but students who skip the Create task or avoid programming practice tend to struggle. The exam rewards students who understand concepts broadly and can apply them to new scenarios.
70 questions in 120 minutes, worth 70% of your score. The section includes 57 standard single-select questions, 5 single-select questions tied to a reading passage about a computing innovation, and 8 multi-select questions where you pick exactly 2 of 4 answer choices. All questions have four answer options and there is no guessing penalty.
Worth 30% of your score. You get 9 in-class hours to write a program, record a short video of it running, and prepare a Personalized Project Reference (PPR). On exam day you answer 4 written-response prompts about your project in 60 minutes, with your PPR available to reference.
The course big ideas include Creative Development, Data, Algorithms and Programming, Computing Systems and Networks, and Impact of Computing. MCQ questions pull from all five areas, and your Create task must demonstrate a working program with a list, a procedure, and an algorithm that includes sequencing, selection, and iteration.
Because the Create Performance Task is submitted before the May exam and counts for 30% of your score, it cannot be made up with last-minute studying. Students who treat it as a checklist item rather than a scored artifact often lose points on the written-response prompts because they cannot clearly explain how their program works. Build a program you genuinely understand, document your PPR carefully, and practice explaining your algorithm and list in plain language before exam day.
A full breakdown of the MCQ section: 70 questions, 120 minutes, question types, pacing strategies, and the wrong-answer patterns that appear most often. This is the 70% of your score you can directly prepare for with targeted review.
Everything you need to know about the Create task: the 9-hour in-class timeline, what your program must include, how to write your PPR, and how to prepare for the 4 exam-day written-response prompts about your own project.
An honest look at where AP CSP is approachable and where students run into trouble, including the Create task pressure points and what it takes to be prepared for both sections of the exam.
The 70-question MCQ section runs 120 minutes, giving you roughly 1 minute 42 seconds per question. Pacing matters most on the multi-select questions, which require you to evaluate all four choices carefully before committing to two answers. The innovation-focused passage questions test reading comprehension alongside computing concepts, so budget a few extra seconds to read the scenario before answering.
Can you identify which question type you are looking at within the first few seconds of reading it? Recognizing multi-select questions immediately prevents accidentally choosing only one answer.
| Question type | Count | Strategy |
|---|---|---|
| Single-select (standard) | 57 | Move at steady pace, flag and return if stuck |
| Single-select (passage) | 5 | Read the scenario first, then the question |
| Multi-select | 8 | Evaluate all 4 choices before selecting 2 |
The Create PT has two scored components: the artifacts you submit (program code, video, PPR) and the written-response prompts you answer on exam day. The prompts ask you to describe your program's purpose, explain how your list manages complexity, trace through your algorithm, and identify an error or change. Your PPR is a printed reference you bring to the exam, so it must accurately reflect your submitted code.
Can you explain out loud what your program does, how your list stores and uses data, and how your procedure works step by step? If you cannot explain it without looking at the code, practice before exam day.
| Component | Submitted when | Used on exam day |
|---|---|---|
| Program code | By end-of-April deadline | Referenced via PPR |
| Video | By end-of-April deadline | Not available on exam day |
| PPR | By end-of-April deadline | Printed copy provided during written response |
Your composite AP score combines the MCQ section (70%) and the Create Performance Task (30%). There is no penalty for wrong answers on the MCQ, so you should answer every question. The Create task is scored by AP readers using a rubric that evaluates your written-response prompts against your submitted artifacts. Points are not awarded for the program itself in isolation but for how well you explain and demonstrate understanding of it.
Do you know which written-response prompt type asks you to trace your algorithm versus which asks you to identify a program error? Reviewing the prompt categories before exam day reduces surprises.
| Section | Weight | Timing |
|---|---|---|
| MCQ | 70% | 120 minutes on exam day |
| Create PT written response | 30% | 60 minutes on exam day |
| Create PT artifacts | Included in 30% | Submitted before exam day |
The Create PT is scored on your written-response prompts, not on how impressive your program is. Students who build complex programs but cannot clearly explain their list, procedure, or algorithm in writing often score lower than students with simpler programs they understand deeply.
Multi-select questions require exactly 2 answers. Selecting only one earns no credit even if that one answer is correct. Always double-check that you have selected exactly 2 choices before moving on.
The 5 innovation-focused passage questions introduce a computing scenario you have not seen before. Students who skim the passage and jump to the question often miss context that changes the correct answer.
If your PPR shows a version of your procedure or list that differs from what you actually submitted, your written-response answers may not align with what readers are evaluating. Verify consistency before the deadline.
There is no penalty for wrong answers, so a blank answer is always worse than a guess. If you are stuck, eliminate what you can and choose the best remaining option before moving on.
Your MCQ raw score and your Create written-response score are calculated separately and then combined at the 70/30 split. A strong MCQ performance can offset a weaker Create score and vice versa, so neither section should be ignored in your preparation.
The Personalized Project Reference is the bridge between your pre-submitted artifacts and the written-response prompts you answer in May. Everything you write on exam day about your program will be evaluated against what is shown in your PPR, making accuracy and clarity in that document essential.
The 5 innovation-focused MCQ questions present a computing scenario and ask you to apply course concepts to it. These questions reward students who understand ideas like data privacy, algorithmic bias, or network security well enough to reason about a new example, not just recall a definition.
Check the AP Digital Portfolio to verify your program code, video, and PPR are all submitted before the end-of-April deadline. Late or missing submissions cannot be scored.
Read through your Personalized Project Reference and make sure you can explain every line of code shown. On exam day you will answer prompts directly referencing this document, so surprises are costly.
The written-response prompts ask you to trace your algorithm step by step. Practice walking through your procedure with a specific input value before exam day so the explanation comes naturally under time pressure.
MCQ questions draw from Creative Development, Data, Algorithms and Programming, Computing Systems and Networks, and Impact of Computing. Identify which areas feel weakest and use the topic guides available here to review them.
Multi-select questions require exactly 2 correct answers and are easy to rush. Practice evaluating all four answer choices before committing, especially on questions about algorithms and data.
120 minutes for 70 questions is tight if you spend too long on hard questions. Practice flagging and moving on so you reach every question, including the multi-select and passage questions at the end.
Use the AP score calculator available here to estimate how your MCQ performance translates to an AP score and identify how many questions you need to answer correctly to reach your target.
If you are still in the 9-hour in-class window, prioritize getting a working program with a clear list and procedure before worrying about MCQ review. The Create task has a hard deadline and cannot be recovered with last-minute studying.
The MCQ guide and Performance Task guide available here cover format, question types, scoring, and strategy for each section. Reading both gives you a complete picture of what exam day actually looks like.
Use the three topic guides to find the big idea areas where you feel least confident. Algorithms and Programming and Computing Systems and Networks tend to have the most technically specific MCQ questions, so prioritize those if they feel shaky.
Before exam day, write out answers to the four Create prompt types using your own project: program purpose, list and complexity, algorithm trace, and program change or error. Time yourself at 15 minutes per prompt to simulate exam conditions.
The AP score calculator available here lets you estimate what MCQ score you need to reach a 3, 4, or 5 given your Create task performance. Use it to set a concrete MCQ target and focus your remaining review time accordingly.
