❔ AP CSA & AP CSP – Frequently Asked Questions

Do I need to take AP CSP before AP CSA?

No. AP CSP can be a nice introduction to computing ideas, but it’s not a prerequisite for AP CSA. Many students successfully take AP CSA as their first CS course using structured resources like the unit guides, FRQ archive, and practice exams on this site.

How many hours per week should I study?

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

Is AP CSA harder than AP CSP?

Generally yes. AP CSA is more code-heavy and math/logic oriented, while AP CSP is more conceptual and broad. AP CSA often feels challenging at first, but becomes much more 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 path (like the AP CSA and AP CSP unit hubs), write code regularly, and ask for help when you’re stuck. The resources and tutoring on this site are designed with beginners in mind.

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. Even if credit isn’t guaranteed, the skills you gain are valuable for future CS courses.

How can tutoring help my student?

Tutoring can accelerate understanding, fill in gaps, and keep students accountable. With individualized explanations and targeted practice, students often see faster improvement in grades, confidence, and exam readiness compared to studying alone.

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.
