The Advanced Placement (AP) Computer Science Principles exam is a critical assessment for students interested in computer science and programming. This exam not only evaluates your understanding of fundamental computer science concepts but also assesses your ability to apply these principles to real-world problems. In this article, we will provide you with an exam review, covering the format, key topics, and tips to help you excel in the AP Computer Science Principles exam.

 AP Computer Science Principles Exam Format

The AP Computer Science Principles exam consists of two parts: the Create Performance Task and the Explore Performance Task. These two tasks make up your entire AP score.

1. Create Performance Task (CPT):

   - In the Create task, you will work on a programming project and create a computer program to solve a specific problem.

   - You will write and submit a program (code) as well as a written response that explains your code's purpose and functionality.

2. Explore Performance Task (EPT):

   - In the Explore task, you will examine a computing innovation or issue.

   - You will choose a computing innovation and write a report explaining the innovation's impact, potential benefits, and challenges.

The AP Computer Science Principles exam does not have multiple-choice questions or a traditional written exam. Your performance on the Create and Explore tasks, each scored out of 24 points, contributes to your overall AP score.
