Good Facts to Know

• If you'll lose 5 minutes of your time over your lifetime because you didn't know something, it's worth memorizing it with Anki. [1]

Card Design

• Include context clues for cards. For example, I might have a card "What does the PG provide?" with an extra field called "Context" to display "Ceph" on the card. This helps because I can mix all of my decks together without getting topics from different subjects confused with one another.
• Do not include hints to the answer. If the hint is necessary, it should be part of the question and displayed by default.
• Include a source field. Even if it isn't visible on the card, it's useful to have recorded in case you need to verify the information.
