As I am in Yr13 I don't have any on me however, I did get an Eight for English LIT and 7 for Language, and what helped me to do so was to analyse quotes in depth different interpretations and techniques and memorise the historical context and link to ur analysis and explain why this AO3 is contributing to the character's portrayal.
I did Inspectors calls and after all the analysis I did LODES of exams Q's and did essays for EACH CHARACTER AND THEME IN THE PLAY and guess what Mrs.Birling came up!!
For Jekyll and Hyde again lodes of exam Q's I recommend CGP for exam Q's as they predict well.
make sure u give in ur essays for teachers to mark!!
English Language is just pure practice of your A02 skills and literary techniques I remember I did not do much revision on Language but still did lodes of exam practice, as I was the first year to do 9-1 I used CGP practice papers but you can use the previous years papers of course!!
Hope this helped lol!!
