Recognize first, then fill a gap, then hear it, then say it. Each review uses a real line you haven't seen for this word in the last two sessions. The topic strip at the top carries the interest where you first met the word. The back is the same index card for every format.
Sentences come from real feed lines that contain the word. When fewer than three exist, the context bank supplies one checked line so the same sentence never repeats back to back.
On Read, the flashcard stays pure white paper. In Review and Words, a thin topic strip recalls where you met the word.
