Short, spaced-repetition cards covering definitions, formulas, and key facts for Grade 12 Physical Sciences. ### Are the cards pre-made or do I make them? Both. Hlayiso ships curated decks per Grade 12 Physical 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. --- Hlayiso: free CAPS and IEB past papers, memos, notes and study guides for South African learners.
