Hi, I'm going into year 13 this september and have mocks after christmasI was just wondering when to start revising for them as I want to get the best grades possible (so that I'm prepared for the real thing)I was going to start in September and do some light revision of year 12 content but I'm finding it really difficult (and boring) as I revised really hard for my year 12 end of years and know everything so what should i do?
