2.	Master the First 100 Cards – Remember the story vaguely for each using pegs 00–99 as anchors.
3.	Master the Next 100 Cards – Use pegs 500–599 as anchors for these cards, following the same method.
4.	Track Your Learning – Use the XYdata peg to review each peg at least 4 times. The AI FSRS monitors your progress and adapts to your memory patterns.
5.	Follow AI Review Schedule – The AI FSRS will tell you when to review each peg (via peg status) to maintain ~95% recall.

Learn Anything, Fast: Once your pegs are secure, use them to lock in new information—like vocabulary for kids—with the help of vivid, AI-generated images.
