## Frequently asked questions

### What are Hlayiso flashcards?

Short, spaced-repetition cards covering definitions, formulas, and key facts for Grade 12 Life Sciences.

### Are the cards pre-made or do I make them?

Both. Hlayiso ships curated decks per Grade 12 Life Sciences 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.

### Can I study offline?

The Hlayiso app keeps your active decks on your device, so you can review without a connection.
