Advanced Placement (AP) Computer Science 2025 - Free AP Computer Science Practice Questions and Study Guide

Advanced Placement (AP) Computer Science can be a challenging yet rewarding course that offers students the opportunity to earn college credit before even stepping foot on a campus. Let's dive into everything you need to know to crack the AP Computer Science exam—from exam formats to essential preparation tips.

Understanding the Exam Format

The AP Computer Science exam is typically divided into two main categories: AP Computer Science A and AP Computer Science Principles. Each focuses on different core aspects of computer science.

AP Computer Science A

• Format: This exam consists of two sections.

• Section I: Consists of 40 multiple-choice questions to be completed in 90 minutes.

• Section II: Involves four free-response questions also covered over 90 minutes.

• Content Areas:

• Object-oriented programming

• Algorithms and their complexity

• Data structures, particularly lists, stacks, and queues

• Programming Language: All coding questions must be answered in Java.

AP Computer Science Principles

• Format: This is broken down into two main parts.

• Create Performance Task: A project where students must develop a computer program of their choosing and reflect on their development process.

• End-of-Course Exam: 70 multiple-choice questions to be answered in 120 minutes.

• Content Areas:

• Data and information

• The Internet

• Algorithms and programming

• Societal impacts of computing

What to Expect on Exam Day

• Timing: Make sure you know the length and timing of each section, so you can pace yourself and allocate sufficient time to navigate both multiple-choice and free-response questions.
• Environment: Expect a structured exam setting. No additional notes or textbooks are allowed, so preparation is key.
• Types of Questions: Plan for a mix of theoretical questions, logical problem-solving, and coding snippets.
