Time to put everything else to one side for now. Make sure there is no distractions around you when you are meant to be doing school work. School work only takes up so many hours. Once that is done you can have all the fun you want to have. So, if it was me, I would clear my room of all distractions. Just have what I need for my school work and nothing else at all. I would even lock the bedroom door. Just so it sinks in just how important this really is.
