Flashcards — Spaced Repetition Review

Flashcard decks for each curriculum level. Cards test recall of key concepts, syntax patterns, and common pitfalls.

Quick Start

# Review all due cards
python practice/flashcards/review-runner.py

# Review a specific level
python practice/flashcards/review-runner.py --level 0

# See your stats
python practice/flashcards/review-runner.py --stats

How It Works

The runner uses the Leitner box system:

Box Review Interval Meaning
1 Every session New or recently wrong
2 Every 2 days Getting it
3 Every 4 days Know it
4 Every 8 days Solid
5 Every 16 days Mastered
  • Correct answer → card moves up one box
  • Wrong answer → card drops back to box 1
  • Cards are shown front-first; you think of the answer, then press Enter to reveal

Progress File

Your review progress is saved to practice/flashcards/.review-state.json (git-ignored). This tracks which box each card is in and when it's due for review.

Tips

  • Review daily, even for just 5 minutes
  • Don't peek at the back — test yourself honestly
  • If a card is too easy, you'll naturally see it less often
  • If you keep getting one wrong, go back to the concept doc
