AP Computer Science Principles

The exam includes 2 components : the Create Performance task and the end of course multiple choice exam. The performance task is 30% of your final score and you’ll be given at least 12 hours in class to work on it. For this part of the exam, you’ll develop a computer program of your choice: one that solves a problem, enables an innovation, or helps you express personal interests. The end-of-course multiple-choice exam is a paper-and-pencil written exam with 70 multiple choice questions that makes up 70% of your final score. To make sure you’re prepared enough to finish in time, take a look through our free AP Computer Science Principles study guide that covers the most important material you should know.
