hi I'm sitting my gcses at the moment and I'm predicted 9s in both of these subjects so hopefully I can help. I would say for history stay on top of content however works best for you- flashcards, mindmaps etc and just try lots of practice questions- really get to know the question structure because its different for each paper. for English lit practice is best! re-read the texts your studying it really does help even if that seems like a lot of effort, learn your quotes- flashcards is great for this! try massolit lectures because they do some really good breakdowns and contexts of the text- especially if your aiming for a higher level. mr bruff on youtube does some good videos too. when writing a response use a set structure- i don't know what you've been taught but i do topic sentence, quote- analysis using key subject terminology (define- what does the word mean, explore- so what could this suggest and effects, connect- link to other parts of the book or another quote e.g if its an extended metaphor find where else its used) and do birds eye view and authors intention- get in context too- this can be historical or just deeper meanings. and honestly for English Lang- I don't really revise but practice papers are good- just know the structure of every question well.
