Exam Information

The College Board AP Computer Science exam lasts for 3 hours, and it has two sections - multiple-choice questions and a free-response section.

  • Section 1: Multiple choice sections have 40 questions, and it lasts for 75 minutes. It covers 50% of your score.
  • Section 2: Free response section has 4 questions and lasts up to 105 minutes.

You need to write the code on a piece of paper. You cannot compile and run it using a computer.

What Is Tested On The AP Computer Science Exam?

The AP computer science course and the test will be instructed using the Java programming language. As an object-oriented programming language, it has similar features to other popular programming languages. There are 5 main concepts tested on the AP computer science exam. These concepts will be taught throughout the year, and you will need to understand them to score well on the exam.

Program Design and Algorithm

The first concept is the program design and algorithm. This section will test your knowledge of what types of code segments are required to produce a given output. It will help students understand what types of programs are needed to solve specific problems. This core concept will also test students’ ability to choose correct code segments to add to already completed programs.

Code Logic

This core concept will focus on the logic behind programs and code. It will test the ability of students to determine the output of a series of coding statements. This concept will test how many times a code segment will execute and when the method will call a specific class or statement. This section makes up 40-45% of the multiple-choice questions on the exam, so we recommend studying it well.

Our guide on how to study for an AP exam might come in handy, so feel free to check it out.

Code Implementation

This section is tested using free-response questions. This core concept will test how well a student can write program code to identify, call, and create objects within a class. You will also see questions that require students to write and manipulate ArrayList objects and 2D array objects. Students will be required to write conditional statements, expressions, boolean expressions, and iterative statements.

Code Testing

Your code must be readable and testable, so the AP computer science exam will also test your ability to use test-cases to find program errors or validate code functionality. Students will also be expected to identify coding errors and determine if two or more code segments will produce the same output.

Documentation

This core concept will require students to analyze code documentation and determine their behavior and compilation. Students will need to understand why a code segment will not compile or run based on coding documentation. They will also have to explain why a program output will change based on changes to the initial code. This section is geared more towards explaining and understanding the programming process than writing actual code.

3 Tips For Succeeding On The AP Computer Science Exam

1. Focus on the Goals of the Test

You should know exactly what types of questions will be on the exam. You should have a thorough understanding of the core concepts you will need to know in the Java programming language. The core concepts we laid out above are essential study tools for you to succeed.

2. Take Online Courses in Java

Many free online resources can teach you the basics of the Java programming language. You should sign up for as many as possible. Many of the free options online are pretty fun and can keep you motivated before exam day. We also recommend using one of the AP computer science books we recommended to supplement your learning.

3. Practice, Practice, Practice

It is no joke that practicing and learning from mistakes will help you succeed. We recommend practicing coding every day. If you run into an issue with your code, you should step back and analyze it to find the problem. You should try different techniques and rerun the code until you get your desired output. Practicing and making mistakes will help you solve your initial problem, understand coding logic, and perhaps learn new things along the way.

FAQs

Is the AP computer science exam hard?

It depends on how well you know the course material. According to the AP College Board test results, 69-72% of students pass the exam. The passing score is 3 or higher to earn college credits.

Can you take the AP computer science course and exam with no prior experience?

Yes, you can enroll in the course without experience. We recommend gaining a rudimentary understanding of programming principles before enrolling, but you will learn most of the basics in the course itself.

Is it easy to self-study for the AP computer science test or should I take a prep course?

It is one of the easier exams to self-study for since most of the material is on the internet. After all, most computer programmers are actually self-taught. If you feel like you need extra assistance and want guidance, then you can ask your AP teacher for a prep course recommendation or tutoring.

Do I need to know any other languages besides Java for the AP computer science exam?

No, but you should definitely understand general programming principles and basics that apply to all object-oriented languages.
