Flashcards · in every pass
Write it. Flip it. Grade it.
Run any set of questions as index cards. Read the stem, write your answer on the card, flip it to check against the cited answer, then grade yourself. Cards you miss come back sooner.

Miscellaneous · Applied biostatistics: number needed to treatA randomised trial of adjuvant therapy reports that 3-year overall survival is 70% in the treatment arm and 60% in the control arm. A trainee is asked to express the benefit as the number needed to treat (NNT) to gain one additional survivor at 3 years. What is the number needed to treat in this trial, and what does that number mean?
The demo runs the free question of the day. Grading and the review queue need a pass.
Three moves, half a minute a card
Pick a site and a question type, then a deck of 10, 20 or 40. Cards due for review come first, then ones you have not seen. Every one of the 2,500+ questions carries the same cited explanation as a card.
Write
The front of the card is the stem alone, with ruled lines under it. Write the answer you would give in the exam before you look.
Flip
The back shows the correct option, the explanation and the source quote with its citation, and what you wrote underneath.
Grade
Got it moves the card up a box; Missed it sends it back to box one. Five boxes, reviewed at 1, 3, 7, 14 and 30 days, never scheduled past your exam date.
