Modern day method to waste time and 'recap' over all those topics you've been 'learning' all year usually in
preparation for a text or exam. For most students, resulting in no help whatsoever when sitting the test
the next day.
Thus student failing test anyway because
revising is innefective due to student thinking about their crush/dinner/myspace/friends for the duruation of the revision period whilst blankly reading through text and making notes they will later misplace.
