culture
Huge industry around the gaokao (高考, 'college entrance exam') and civil-service tests. Star teachers who 押题 well — 押中 (yāzhòng, 'guessed right') — get a near-celebrity following.
memory
押 'to bet/wager' + 题 'question' — literally 'to bet on which questions will come up.' The gambling metaphor is alive: a teacher can 押中 ('hit the jackpot') or 押错 ('bet wrong').
