What I basically meant was, spend one day/few hours, plan out everything you want to do, and then actually do it, dont be like, oh no I woke up late, I'll start tomorrow, OR I'll start at the next stage of my plan for the day, then you miss that and you'll say, maybe the next part of the plan/next subject, etc... dont do that.
Just memorize your content for everything, and do past papers 2 weeks before exams, nothing else, make sure you know your content really well before you start papers.
