Didn't listen in class for vast majority of Year 10 in Biology, Chemistry, Physics, Maths and Geography, and now I get to pay the price for that! I'm planning on doing about 64 hours of going through topics this half term (already done three days of 6/7 hours per day) and 3-4 hours a day after half term so I can get my grades up before the winter mocks (mainly in maths to see if I can get into set 1). I'm aware that's very excessive for GCSE, but I feel really guilty when I play games all day so...
If you're in Year 10, please listen in class so you don't get to do what I'm doing (learning a tonne of content from YouTube and revision guides in my own time). For a little bit of effort in class, you get a lot out of it by not having to do what I'm doing and instead having a much less time consuming and much easier process of revision.
If you're in Year 11 and you're in my shoes, you don't have to do what I'm doing by any means, but at least put some time into work into it so you don't have to rush a few weeks before your exams.
