The way I see it.... I had an awesome history teacher in high school. He would tell us the test questions and the test answers, a few days before the scheduled test was to be taken. His reasoning for this ??? Since he mixed all the questions up during the actual testing, and he incorporated multiple choice as well, he believed a student would study until he remembered the questions verses the answers. And !! He was right ! Those who actually memorized the test questions and answers, done well. Those who tried to cheat, since no two tests were alike, yet all answers and questions were, flunked.
