EyeCertPrep is an independent study resource and is not affiliated with or endorsed by JCAHPO.
It learns what you don't know. Then it drills it.
Every session, EyeCertPrep tracks your answers and reshapes what comes next — automatically. No other COA prep product on the market does this.
Every answer — right or wrong — is recorded. The platform scores each question by domain and difficulty.
Any of the 22 COA domains where you scored below 70% is surfaced immediately. No manual filtering — it tells you exactly where you failed.
Questions you've gotten wrong are weighted 3× heavier in the next session. The ones you've mastered fall back. Your weakest material always loads first.
Questions graduate through buckets — needs work, in progress, mastered. Mastered questions are skipped for 3 days then reintroduced. Study time goes where it's needed.
Examzify claims "adaptive." We built it.
Competitors randomize questions and call it adaptive. EyeCertPrep scores every domain after every session, weights missed questions by frequency, and redistributes study time to where you actually need it — automatically, every time you open the app.
⏰ Students who start studying 8+ weeks before their exam report better outcomes
Why I Built This
I built EyeCertPrep because the available study materials didn't match what I actually needed to know for the exam. They were generic, outdated, and lacked clinical relevance.
I used my own tool to retake the COA—and passed. Now I'm sharing it with anyone preparing for the exam. Not as a textbook company. As someone who's been exactly where you are.
— Brian McDonald, Ophthalmic Technician and Founder
