So this is one problem that plagues all. Some people are rational and take breaks once every week, like Monday ( when no tests are to be written ). others go on studying without a break, until after 10-11 days, there is a breakdown and then they end up wasting3-4 days. Yet some people are able to study for 15-20 days with some 3-4 days unplanned break after that?
What do you do / end up doing?
