A long time back I did Baltimore Catechism flashcards using Anki, but that was relying on a computer program to work through the flashcards.
Someone lamented the lack of free Catechism resources for Catholics.
Here’s an attempt.
And here are the source files: baltimore-flashcards.tex, mya4cards.cfg
I used the Baltimore Catechism Book 1 from Project Gutenberg. They also have Book 2 and Book 3 and Book 4, so it would be possible to do the other books, though I can’t see a quick way.
