It's reviewing information at increasing intervals — right before you'd forget it. Research consistently shows it boosts long-term retention, cuts total study time, and beats cramming. Anki automates it by tracking your performance and timing each review for you.
No. The decks are free, and Anki is free on desktop, web, and Android. Only AnkiMobile (iOS) is a paid app — everything else, including cross-device sync via AnkiWeb, costs nothing.
Absolutely. Once imported, the deck is yours — rewrite cards, add notes, suspend ones you know cold, or merge it with your own collection. The .apkg is a starting point, not a cage.
If you're newer to SQL, SQL Bolt builds up gently through queries and joins. SQL W3Schools is a broader reference sweep. They overlap nicely — many people run both.
