ABOUT

AP®︎ CHEMDUNN combines quality AP®︎ Chemistry content with the science of how we actually learn. Grounded in neuroscience research, the app is designed to help students retain more, stress less, and perform their best on assessments and the AP exam. It's not just what you study — it's how you study it.

Our Process

Smarter Study Habits

Scheduled mode prompts students to practice at times they choose, building the spaced repetition and soft accountability that neuroscience identifies as key to long-term retention. Questions are AP teacher written — NOT generated by AI.

Instant Help Flag

Every question includes a "Flag Question" feature, allowing you to mark difficult problems and attach a note in the moment. These are sent to your tutor creating a custom study list of your specific sticking points for review later.

Know Your Gaps

A detailed score report breaks down performance by unit and individual topic, giving students — and their tutors — a clear, real-time picture of exactly where to focus.

  • "I went from barely passing my unit tests to getting a 5 on the AP exam. The score report showed me exactly what I didn't know, and the scheduled reminders actually kept me consistent for once."

    —AP Chemistry Student

  • "My daughter has always struggled with staying on top of studying, but the app gave her a structure she could actually stick to. Watching her confidence grow throughout the year made me so happy."

    —Parent

  • "As a tutor, I used to spend the first 10 minutes of every session just figuring out where a student was struggling. Now I walk in already knowing — and we spend that time actually solving the problem."

    —Justin, Tutor

  • "I recommend AP CHEMDUNN to every parent I work with. The tutor connection feature means I'm not just guessing at what a student needs — I have the data to back it up and the ability to step in before a student falls behind."
