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.
