GCSE help

Im currently in y11 and as you all know it's January now. For some context before I get to my main question, my mocks were completed in Nov after the half-term break and I'm getting my results next week but I've got my marks already so I can make an educated guess on the grade boundaries. I really need some tips like for my physics mock exam I did every single question which could come up and that's all I did. Can I get some tips, I know past papers and other stuff work but like what would a typical study session genuinely look like for a grade 9 student as Im so lost. I realised my potential too late and I have wanted all 9s since the y10 mocks. Plssss anyone
