As of the 2014-15 school year, the GridWorld case study was replaced by a required lab component consisting of a minimum of 20 hours of hands-on lab experiences.
Three AP Computer Science A labs are available as exemplars to support the implementation of at least 20 hours of hands-on lab work in the classroom. Teacher guides with solutions are available through teachers' AP Course Audit accounts, and student guides are available on the AP Computer Science A Lab Resource Page.
Teachers will have the flexibility to modify and implement these labs according to the needs of their students and to use other, comparable labs and resources to meet the 20-hour lab requirement.
The 2016 AP Computer Science A Exam will not have specific questions that focus on the AP Computer Science A labs and will continue to assess the concepts and skills outlined in the Course Description. In addition, there will no longer be any GridWorld case study questions. A practice exam is available for teachers through their AP Course Audit accounts.
Teachers with previously authorized courses are not required to revise and resubmit syllabi.
