Both exams measure a student's understanding and proficiency in computer science topics and can be counted as college credit, depending on a student's final score and the college requirements.

This article shares everything students and parents need to know about the APCSP exams. Learn the test dates, get study resources, and discover the best practice exams so students feel confident and prepared when test day comes around.

What’s the APCSP Exam?

The APCSP Exam (AP Computer Science Principles) is one of the two computer science AP course/exam combinations offered by the College Board.

Both AP Computer Science Principles and AP Computer Science A are introductory college-level computing courses that expose students to the field of computer science. Students learn about the disciplines, principles, and science of computing by developing programs and designing solutions to real-world problems. This includes gaining critical thinking skills, solving problems using algorithms, and understanding the foundation of computing systems, like the internet. The aim is for students to begin addressing real-world problems using computation tools and processes, and exploring the impact of their solutions to contribute to a fair, ethical computing culture.

While each AP Computer Science exam is different, both measure students' proficiency in computing concepts and contribute to the final AP score. This is done through performance tasks, multiple-choice questions, and free-response questions. Let's explore the format of each exam.

Explore the APCSP exam format

The two AP Computer Science exams have different formats in order to reflect the material learned throughout each course.

AP Computer Science Principles Exam

The AP Computer Science Principles exam has two parts: a Create Performance Task that's completed during the course and a multiple-choice exam that's given at the end of the course. The Create Performance task accounts for 30% of the final exam score, and the multiple-choice exam accounts for 70% of the score.

Part I: Create Performance Task

Students develop a computer program of their choice that solves a problem, showcases an innovation, or expresses their personal interests. According to the College Board, the task must include:

  • A video of the program running
  • Individual written responses about the program and development process
  • Program code

Every student should have a minimum of 12 hours of class time to finish the task, which is submitted through the online AP Digital Portfolio for scoring.

Part II: Multiple-Choice Exam

Students have two hours to complete the 70-question test, which contains three types of questions:

  • Single-select questions (57 questions)
  • Single-select questions based on a reading passage (5 questions)
  • Multi-select questions (8 questions)

The questions revolve around five major ideas in computing:

Both the Create Performance Task and the multiple-choice exam contribute to the final AP score range of 1-5.

AP Computer Science A

The AP Computer Science A exam is an end-of-course written test that features two sections: multiple-choice questions and free-response questions.

Section 1: Multiple Choice

Students have 1.5 hours to answer 40 questions, including single questions and sets of two questions. In this section, the College Board asks students to:

  • Determine the required code segments to produce a given output
  • Identify the output, value, or result of a given program code based on initial values
  • Analyze program code for correctness, equivalence, and errors
  • Describe the behavior and conditions that lead to results in a program

This section account for 50% of the final AP score.

Section 2: Free Response

Students have 1.5 hours to answer four free-response questions that focus on code implementation. The College Board creates these questions based on the following topics:

  • Question 1: Methods and Control Structures. Students are asked to write program code to create objects of a class and call methods, and satisfy method specifications using expressions, conditional statements, and iterative statements.
  • Question 2: Classes. Students are asked to write program code to define a new type by creating a class and satisfy method specifications using expressions, conditional statements, and iterative statements.
  • Question 3: Array/ArrayList. Students are asked to write program code to satisfy method specifications and create, traverse, and manipulate elements in 1D array or ArrayList objects.
  • Question 4: 2D Array. Students are asked to write program code to satisfy method specifications and create, traverse, and manipulate elements in 2D array objects.

This section account for 50% of the final AP score.

While each test requires hours of studying, practice exams, and actual test-taking, a good final score can be a major benefit for students.

All AP exams are administered at high schools or approved exam centers. Students can start by asking a teacher or school counselor if their school gives the AP Computer Science exams. If so, they can ask to sign up.

If a school doesn't administer the exam, students will have to sign up to take it at a different local school or local center. You can find a list of the official, up-to-date schools and centers that administer AP exams on the AP Course Ledger. These places have passed the AP Course Audit and may allow outside students to test at their location.

Once you've found a list of schools that administer the AP Computer Science exam you're interested in, find the phone numbers and ask to speak with the AP coordinators. This person will let you know if outside students are allowed to test at the school. They can also order the test materials, collect test fees, and help coordinate when and where students report for the exam.

Note: Many schools have deadlines and policies for allowing outside students to test at their facilities. To improve students' chances of taking the exam, contact the schools as early as possible. The AP Course Ledger for 2021-2022 is updated in November, so check back throughout the month to see if any schools in the area were added to the list.

The AP Computer Science exams are scored by the College Board and a group of experienced educators called AP Readers. After the exams are complete, schools return the paper AP exams to the AP program for scoring.

  • The multiple-choice section is scanned and scored by computer, and the total number of correct answers becomes the score for that section.
  • The free-response questions and performance tasks are scored by trained college professors and AP teachers. This happens during the annual AP Reading in the first two weeks of June.

The total scores from each section are combined to create a composite score, which is translated into the 5-point scale using statistical computing. The goal is to ensure that a 3 from the previous year of testing shows the same level of success as a 3 from the current year.

The range of scores differs every year, but here's a look at what the distribution looked like for the 2020 AP Math and Computer Science exams:
