Plan for the AP Computer Science A Exam

When is the AP Computer Science A Exam?

The AP Computer Science A Exam is usually scheduled in the first 1-2 weeks of May. The exam lasts 3 hours and consists of two sections: multiple-choice questions and free-response questions. For more information on exam dates and times, students can refer to the full schedule on the College Board website.

How to study for the AP Computer Science A Exam?

Success in AP Computer Science requires a strategic approach. Students should:

Study Consistently: Coding is a skill that improves with regular practice. Dedicate time each day to write and debug code. Use online platforms like to find exercises and challenges that will help reinforce your learning.

Create a Study Schedule: Develop a study plan that includes all the topics you need to cover before the exam. Allocate more time to areas where you feel less confident. Regularly review your progress and adjust your schedule as needed to ensure you stay on track.

Take Mock Exams: Simulate exam conditions by taking full-length practice tests under timed conditions. This will help you manage your time effectively during the actual exam and identify areas where you need further practice. Review your answers to understand your mistakes and learn from them.

Engage Actively: Join study groups, participate in forums, and engage in discussions with peers and teachers. Collaboration can provide new insights and help clarify difficult topics.
