Something like the SAT is a game that people learn to win. This is oft claimed, but data doesn't back it up. SAT is marginally affected by coaching and training. "Coached students are only slightly more likely to have large score gains than uncoached students. In addition, about 1/3 of students experience no score gain or score loss following coaching. The typical gain associated with coaching is 8 points for verbal and 18 points for math" https://www.washingtonpost.com/news/answer-sheet/wp/2017/05/09/can-coaching-truly-boost-sat-scores-for-years-the-college-board-said-no-now-it-says-yes/ https://www.washingtonpost.com/news/answer-sheet/wp/2017/05/...
