❔ Frequently Asked Questions

Do I need to take AP CSP before AP CSA?

No. AP CSP can be a helpful introduction to computing ideas, but it's not required. Many students successfully take AP CSA as their first CS course using structured resources like our unit guides, FRQ archive, and practice exams.

How many hours per week should I study?

Most students do well with 3–6 hours per week outside of class. Spread that time between learning concepts, writing code, and practicing FRQs and MCQs rather than cramming.

Is AP CSA harder than AP CSP?

Generally yes. AP CSA is more code-heavy and logic-oriented, while AP CSP is more conceptual and broad. AP CSA can feel challenging at first but becomes manageable with consistent practice.

What if I've never coded before?

That's okay! Many students start AP CSA or AP CSP with no coding background. The key is to follow a clear learning path, write code regularly, and ask for help when you're stuck. Our resources are designed for beginners.

What score do I need for college credit?

Many colleges grant credit or placement for a 4 or 5 on AP CSA, and some accept a 3. AP CSP credit varies more widely. Always check the policies of the specific schools you're interested in.

How can tutoring help my student?

Tutoring provides personalized explanations, targeted practice, and accountability. Students often see faster improvement in grades, confidence, and exam readiness compared to studying alone.

🚀 Your Next Steps

Ready to start your AP CS journey? Here's the fastest path to success:

  1. Choose your course: Start with the AP CSA Hub or AP CSP Hub
  2. Follow the unit guides in order (Units 1–4 for CSA, Units 1–6 for CSP)
  3. Practice daily: Use the Daily Practice Questions to build consistency
  4. Practice with real exams: Use our MCQ practice exams and FRQs by Topic
  5. Get help when stuck: Consider 1-on-1 tutoring for personalized support
You don't have to figure this out alone. With clear resources, consistent practice, and expert support when you need it, AP CSA and AP CSP become not just manageable—but genuinely rewarding.

Why I Created AP CS Exam Prep

I built AP CS Exam Prep to give students and teachers a clear, supportive, and reliable path through the AP Computer Science courses. Too many students struggle to find trustworthy resources, and too many teachers spend countless hours trying to curate materials on their own. I wanted to fix that.

AP CS Exam Prep brings everything together in one place—practical study guides, curated resources, video walkthroughs, and personalized tutoring—all designed to help students build real confidence in both AP Computer Science A and AP Computer Science Principles.

Over my years as an AP Computer Science teacher and tutor, I’ve seen exactly where students get stuck, what concepts need more clarity, and what actually helps them succeed. This website is built around that experience.
Whether it’s mastering core Java concepts for AP CSA, strengthening your understanding of essential AP CSP ideas, or building confidence through real practice questions, my goal is simple:

Make AP Computer Science easier to understand, easier to practice, and easier to master.
