Cards
Young cards come back within three weeks. Mature cards have gaps of 21 days or more, the line Anki uses.

Memory lab
Your recent answers
Settings
The chance of remembering a card when it comes back. A higher target brings cards back sooner, so there are more reviews; the Anki manual notes that above 90% the number of reviews rises steeply.
For each deck.
With a date set, every card you have started comes back at least once before the exam, on the day before it at the latest. Cards you have not started yet are not included.
Memory lab
Compares ways of answering, to see which helps you remember. In each deck, new cards are split at random between the styles below, and each is checked two days after it is learned by typing its answer. After ten checks for each style, the lab says whether one is clearly ahead for you, and new cards then lean towards the one doing best. The check is typed, so the typing style practises the check’s own format, which may give it an edge.

How it works
- Each card asks before it shows: anatomy cards highlight a structure on a real MRI or CT slice and ask for its name. Testing yourself this way is remembered better than reading the answer again (Rowland 2014; Yang and colleagues 2021).
- After every attempt you see the right answer. This matters most after a wrong answer (Pashler and colleagues 2005; Rowland 2014).
- A card you miss comes back in the same sitting until you get it, then again on later days (Rawson and Dunlosky 2022; Higham and colleagues 2022).
- Cards come back after gaps that grow as you remember them, each gap set from your own answers to that card and your recall target. Spreading reviews out beats cramming (Cepeda and colleagues 2006; Latimier and colleagues 2021). The timing uses FSRS-6, an open-source scheduler.
- Anatomy cards pick a slice at random each time, avoiding the one you saw last time: either side, any plane, and for the spine any of its scans, always one where the structure shows clearly.
- How a session feels is a poor guide to what you will remember later (Kornell and Bjork 2008; Kirk-Johnson and colleagues 2019), so the memory lab goes by a check two days later instead.

About the decks
Axial and coronal images follow the radiological convention: the patient’s right is on the viewer’s left. Sagittal images have anterior on the left. Letters at the image edges show the directions.
