The 2024 AP Computer Science A exam varied significantly between the U.S. and International administrations. While both assessed core Java principles and object-oriented design, the structure and cognitive demand of the questions differed in key ways. Here's a full comparison to guide students and educators preparing for 2025.
| Aspect | U.S. Version | International Version |
|---|---|---|
| Overall Difficulty | ⭐⭐⭐☆☆ | ⭐⭐⭐⭐⭐ |
| MCQ Focus | Array traversal, Boolean logic, class interaction | Reference tracing, inheritance, method return chains |
| FRQ Structure | Procedural method writing, 2D arrays, basic class construction | Full class hierarchy + overrides, static vs non-static methods, deep polymorphism |
| Recursion | 1 minor mention | 1 conceptual question (non-coding) |
| Emphasis | Clean code and method correctness | Structural reasoning and system-level logic |
The U.S. exam rewarded students who practiced typical Java method writing with strong logic flow. It favored procedural and readable answers with clean structure and correct loop logic.
The International exam leaned heavily into conceptual OOP design. It tested understanding of how object-oriented systems operate, how constructors flow, how methods override each other, and how references behave across interacting classes.
