A deck is a named set of cards. Prerequisite links connect cards within one deck, so keep cards that build on each other together.
A card is what you write. When you study, Armin shows you its review units: a Basic card has one, a reversed card has two (one per direction), and a cloze card has one per deletion. Each review unit is scheduled on its own.
Card types
| Type | What you write | What you review |
|---|---|---|
| Basic | A front and a back. | The front; recall the back. |
| Basic and reversed | A front and a back. | Both directions, scheduled separately. |
| Cloze | Text with hidden parts, such as {{mitochondria}}. |
The text with one deletion hidden at a time. |
| Type the answer | A prompt, an answer, and any other accepted answers. | The prompt; type the answer and Armin checks it. |
| Image occlusion | An image with masked regions. | The image with one region hidden at a time. |
| Concept | A brief and one worked example. | A new exercise from the concept each time. Requires Pro. |
Cloze deletions
Wrap each part to hide in double braces. Every deletion becomes its own review unit unless you number them: deletions with the same number are hidden together.
The {{1::mitochondria}} is the {{2::powerhouse}} of the {{2::cell}}.This card has two review units: one hides “mitochondria”, the other hides
“powerhouse” and “cell” together. Add a hint after a second ::, as in
{{1::mitochondria::organelle}}.
Concept cards
A concept card practises a skill rather than a fact. You describe the concept and give one worked example, and Armin generates a pool of exercises from it. Each review shows a different exercise, while the schedule tracks the concept as one card. You can edit, flag, or delete exercises you don’t want.
Concept cards need a Pro plan. See Plans and limits.
Images and audio
Cards can include images and audio. Armin shrinks images and compresses audio in your browser before upload, and stores them privately in your library.
