The complete collection of AP CSA Free Response Questions (2004-2025) organized by question type. Practice exactly what you need to master.
🎯 Jump to Topic Type
📌 Important: Understanding the Format
Since 2019, the AP CSA exam follows a consistent 4-question format:
- FRQ 1: Methods & Control Structures (20-25 min)
- FRQ 2: Class Design & Implementation (20-25 min)
- FRQ 3: Array or ArrayList Manipulation (20-25 min)
- FRQ 4: 2D Array Operations (20-25 min)
Before 2019, question types varied but are organized below to match current topics.

💡 Proven Study Strategies (From 10+ Years Teaching)
How my highest-scoring students practice:
- Start with one type, master it completely: Don't jump around—become an expert in Array/ArrayList first
- Do 3 from one type in a row: Builds pattern recognition faster than mixing types
- Time yourself after the 3rd attempt: First 2 untimed to learn, 3rd+ timed to build speed
- Rewrite solutions from memory: Don't just read solutions—close them and code from scratch
- Create your own variations: Change one requirement and re-solve (builds deep understanding)
- Track your "mistake patterns": Write down which errors you repeat (off-by-one, null checks, etc.)
Goal: By exam day, you should recognize each FRQ type within 10 seconds and know exactly which pattern to apply.
"This organization saved me so much time! I was weak on 2D arrays, so I did ALL the Type 4 FRQs in 3 days. Went from barely passing to consistently getting 8/9 points. Game changer."

❓ Frequently Asked Questions
Start with Type 3 (Array/ArrayList). It appears on 90% of exams and builds the foundation for the other types.
Aim for 4-6 FRQs per week (one of each type, plus extra on weak areas). Quality over quantity—review solutions thoroughly.
Focus on 2019-2025 first (current format), then add older FRQs for extra practice. The concepts haven't changed, just the organization.
On the exam: 20-25 minutes each. When practicing: take as long as needed untimed first, then practice timed after you understand the patterns.
