Spaced repetition is a scientifically-proven learning technique. LingoDeck uses the SM-2 algorithm to show you flashcards at optimal intervals. Cards you know well appear less frequently, while cards you struggle with appear more often. This maximizes retention while minimizing study time.

After revealing a card's answer, rate how well you knew it:

• Again: You didn't know it - card will appear again soon
• Hard: You knew it with difficulty - shorter interval
• Good: You knew it well - normal interval
• Easy: You knew it instantly - longer interval

Be honest! Accurate ratings help the algorithm optimize your learning.
