## Frequently asked questions

### What are Hlayiso flashcards?

Both. Hlayiso ships curated decks per Grade 11 Information Technology topic, and you can create your own decks to share or revise privately.

### How does spaced repetition work?

Cards you get right are shown less often; cards you struggle with come back sooner. Over a few sessions you end up remembering the hard stuff.
