AP Computer Science A Exam Pattern and Scoring
Digital Testing Platform:
The AP Computer Science A exam is Fully Digital and administered via the Bluebook application.
- Section I (MCQ): Questions and code snippets are presented and answered on-screen.
- Section II (FRQ): Students type their Java solutions directly into the testing interface. The digital test includes standard text manipulation features, but auto-complete, code compiling, and syntax checking are disabled.
- Reference Material: The official Java Quick Reference guide is embedded and accessible digitally throughout both sections.
| Section | No. of questions | Weightage | Details |
| Section I: Multiple Choice | 42 questions | 55% | - Includes individual and occasional sets of 2 questions. - Tests ability to: • Determine required code segments for specific outputs. • Identify outputs, values, or results of given program code. • Analyze code for correctness, equivalence, and errors. • Describe behaviour and conditions leading to results in a program. - No calculator permitted. |
| Section II: Free Response | 4 questions | 45% | - Respond with written answers: 1. Methods and Control Structures: Control flow, conditionals, and loops. 2. Classes: Defining a complete class and its behaviors. 3. Array/ArrayList: Traversing and modifying 1D arrays or ArrayList structures. 4. 2D Array: Multi-dimensional array operations and matrix traversals. |
