Exam Format

The AP Computer Science Principles end-of-course exam has consistent question types and weighting every year, so you and your students know what to expect on exam day.

Section I: End-of-Course Multiple-Choice Exam
70 multiple-choice questions | 120 minutes | 70% of score | 4 answer options

  • 57 single-select multiple-choice
  • 5 single-select with reading passage about a computing innovation
  • 8 multiple-select multiple-choice: select 2 answers

Section II: Create Performance Task: Written Responses
30% of score

  • Create performance task program code, video, and student-authored Personalized Project Reference | 9 hours in-class
  • 4 written response prompts | 60 minutes end-of-course exam

The second section of the AP Computer Science Principles Exam consists of a through-course Create performance task where students will develop a computer program of their choice and an end-of-course written response section where students demonstrate their understanding of their personal Create performance task by answering four prompts. Students will be provided 9 hours of in-class time to complete their program, video, and develop a Personalized Project Reference.  

For the written response prompts, students will have access to their Personalized Project Reference and write responses to four prompts related to their program and code contained in this reference sheet. One question from each of the prompt categories listed below will appear on the end-of-course exam. The specific prompts will vary across the different versions of the exam.

Prompt Category

Required Learning Objectives

Program Design, Function, and Purpose 

Students should be prepared to respond to prompts about their program that assess any of the following learning objectives:  

  • CRD-2.A: Describe the purpose of a computing innovation.  

  • CRD-2.B: Explain how a program or code segment functions.  

  • CRD-2.C: Identify input(s) to a program. 

  • CRD-2.D: Identify output(s) produced by a program. 

  • CRD-2.E: Develop a program using a development process. 

  • CRD-2.F: Design a program and its user interface. 

  • CRD-2.G: Describe the purpose of a code segment or program by writing documentation. 

Algorithm Development 

Students should be prepared to respond to prompts about their program that assess any of the following learning objectives:  

  • CRD-2.B: Explain how a program or code segment functions. 

  • AAP-2.E.b: Evaluate expressions that use relational operators. 

  • AAP-2.F.b: Evaluate expressions that use logic operators. 

  • AAP-2.H.b: Determine the result of conditional statements. 

  • AAP-2.J: Express an algorithm that uses iteration without using a programming language. 

  • AAP-2.K.b: Determine the result or side effect of iteration statements. 

  • AAP-2.L: Compare multiple algorithms to determine if they yield the same side effect or result. 

  • AAP-2.M.a: Create algorithms. 

  • AAP-2.M.b: Combine and modify existing algorithms.

Errors and Testing  

Students should be prepared to respond to prompts about their program that assess any of the following learning objectives:  

  • CRD-2.I.a: Identify the error. 

  • CRD-2.I.b: Correct the error. 

  • CRD-2.J: Identify inputs and corresponding expected outputs or behaviors that can be used to check the correctness of an algorithm or program.

Data and Procedural Abstraction 

Students should be prepared to respond to prompts about their program that assess any of the following learning objectives:  

  • AAP-1.D.a: Develop data abstraction using lists to store multiple elements.  

  • AAP-1.D.b: Explain how the use of data abstraction manages complexity in program code.  

  • AAP-2.O.a: Write iteration statements to traverse a list. 

  • AAP-2.O.b: Determine the result of an algorithm that includes list traversals.  

  • AAP-3.B: Explain how the use of procedural abstraction manages complexity in a program.
