Updated on

This deck was modified when it was brought in: Every multiple-choice question in the database has been turned into a single card, question to full-sentence answer: the three distractors are dropped, they mean nothing in active recall. Questions that point at the list of options, at a missing picture or at a state of the world tied to one year have been removed, along with restatements of a question already in the deck, pairs that ask the same fact in both directions, entries with no question mark, and entries found on review to be factually wrong, misspelled, ambiguous, or off the deck’s topic. The HTML entities served by the API have been decoded and invisible whitespace removed. No question or answer text has been rewritten: a faulty entry is removed, never corrected.
