For calc, and my natural sciences for that matter, I would calculate the days left between me and the final and break down the chapters to each day, and then the final day (final's eve- oooo) I would do a quick- several hour- review of everything I covered over the week. Ie: chater 1/2 (thurs), chapter 3 (fri), chapter 4 (sat), chapter 5 (sun), review (tues). Grit your teeth and say 'bye' to weekend fun.
