About the Course

AP® Computer Science A (NCAA Approved)

  • Grade 9+
  • CTY-Level
  • Session-Based

This course offers you a college-level challenge, covering material typically explored in a university course and preparing you for the AP Computer Science A exam. We’ll learn about procedural abstraction, data abstraction, object-oriented design, Java programming methodology, the use of algorithms and data structures, as well as arrays and strings, understanding existing code, and the use of standard Java class libraries.

Along the way, your instructor will guide you through lessons, videos, readings, forum discussions, programming activities and labs, and other interactive resources.

This session-based course provides students with the structure of a set schedule, and has strict deadlines for all graded items. If you prefer a more flexible format, you should consider enrolling in the individually-paced version of this course. The individually-paced AP Computer Science A course covers identical content but provides students with more independence and flexibility.

Time Commitment: 8-10 hours per week (1-hour optional meeting, 8-9 hours of independent work).
