Leitner spaced repetition
Study less.
Remember far more.
The Leitner algorithm tracks what you've mastered and what keeps slipping — then surfaces each card at the exact moment you're most likely to forget it.

How a Leitner session works
Pick a domain, start a Leitner session
Choose the IAAP domain you want to work on. The algorithm pulls cards that are due today — a mix of cards you haven't seen yet and ones that are scheduled for review based on your past feedback.
Read the prompt, recall the answer
A card shows you the term or question. Take a moment to recall your answer before tapping to reveal. Forced retrieval — not passive re-reading — is what builds long-term memory.
Rate your recall honestly
Three options: Correct, Unsure, or Incorrect. Your rating determines which box the card moves to and when you'll see it next. Correct → later box. Incorrect → back to box 1.
Let the schedule do the work
Each box has a different review interval (1 day, 2 days, 4 days, 8 days, 16 days). Cards in box 5 are considered mastered. The algorithm surfaces them all at exactly the right moment.
Why spaced repetition
There's a reason the best language learners swear by it.
Spaced repetition doesn't just help you pass one exam — it builds durable long-term memory. For accessibility professionals, that means the CPACC knowledge you build stays with you throughout your career, not just for the exam.

The forgetting curve is real — spacing fights it
Without review, you forget roughly 70% of new information within 24 hours. Spaced repetition schedules reviews at the moment just before you forget — repeatedly — so each card requires progressively fewer reviews over time.
Leitner is simple enough to trust
More sophisticated SRS algorithms (like SM-2) require calibration. Leitner's 5-box model is straightforward to understand and still highly effective for exam prep, where you need to cover a defined body of knowledge in a fixed time.
CPACC content is perfect for flashcards
Disability models, assistive technology categories, legal framework dates, WCAG success criterion numbers — this is dense, interconnected terminology. Flashcards are ideal for building the fast recall you need in a timed exam.
Sessions under 10 minutes build consistent habits
Long study sessions are hard to maintain. By keeping daily Leitner sessions short, A11yPrep is something you can realistically do every day — and consistency compounds far more than occasional long sessions.
