Org-drill is an Org-mode extension that provides spaced-repetition and flash-card functionality. It has a wonderful documentation on Worg, but somehow I couldn’t get myself to read the whole document, and setup org-drill, until now.

The setup is quite straight forward, once you have org-mode along with the contrib packages. Just (require 'org-drill), and you are all set! To add a new card, all you need to do is add a :drill: tag to the items you wish to “Org-drill”. You can start a review session with simply M-x org-drill. You will be shown flash cards, and you can rate how correct and comfortable you were, in answering the questions. Based on your responses, the cards are scheduled for review. Start another review session, whenever you need one!

What I could only understand once I got myself to read the whole document was that:

• The default scope of a drill session is the current file. But, you can start sessions with scopes like current tree, current directory, or a specified list of files. This is super-useful!

• The review sessions are not automatically scheduled, based on when you schedule failed flash-cards. Scheduling the review for a card only sets a due-date for them, and effects, what you are asked in your next session.

Cram mode and incremental reading are also things I want to try, as I go along.

Happy Learning!
