hi!! i'm very happy to help

i'm glad to know i've done the same exam board as you so this makes it easier for me to help you
prose: now, i do not have advice to aid you on your texts in particular HOWEVER, i know that prose is often the hardest paper to score top marks in but i found a technique that's quite useful:
1) INTRO
2) COME UP WITH 2 POINTS THAT FIT BOTH TEXTS. for example: both texts explore gender through a female perspective, both texts portray gender as a malleable concept (idk just making this up LMAO). with those two points, you can then create 4 paragraphs. 2 paragraphs would be about wuthering heights and the other 2 would be about a thousand splendid suns. this method honestly made it easier for me to include more points and prevented me from over-writing - although with the added paragraph it does make it look like more work.
3) PEEL
4) At the end of each paragraph, ALWAYS write a sentence that compares the two. for example, if you're writing about wuthering heights and its portrayal of gender, at the end when you're about to finish your point, include at least 1 sentence saying 'this could be compared with a thousand splendid suns as they both draw upon comparisons of ___.' this is a nice way to not forget AO4 and to possibly segue to the next para where you expand on this further.
drama: this was my favourite paper by far and streetcar was def my fav text. for this paper, my BIGGEST advice is to TALK ABOUT STAGE CRAFT! so many people focus on the play as another text. however, we must remember it is a performance and much of the effect of the text is through what we see on stage rather than how we read it to ourselves. in your essay, always mention a key feature of how the stage is set up to gain marks. you could do this by watching live versions of the play (the gillian Anderson one is a good performance to reference) and seeing how they set up the stage. BEWARE of over-analysing the stage production rather than the text in front of you as you could lose marks by going off track. however, it is good to reference the different ways the play has been adapted onstage to lift your AO2 and AO3 marks. some stage craft features i would always point out would be how the stage is set up for audiences to witness the interior and exterior of the apartment (showing the intrusion of the new south upon the old south), the significance of the portieres and how during the poker scene the silhouette of blanche's figure could be seen by the men in the other room (conflict between masculinity and femininity).
another piece of advice i have about drama is to learn the conventions of greek tragedy and Shakespearean tragedy. this is something i wish my teachers had embedded in me earlier as i only truly learned about it during exam week itself but PLS LEARN THEM. it won't necessarily come up as an exam question but there is still a chance and ALSO it is very beneficial for you to insert greek tragedy conventions or terminology (if relevant) in your essays to impress examiners.
poetry: for poetry, i would say i struggled with this paper the most throughout the course but during the exams, i performed the best in this one. rlly weird but my advice would be to create a document now (or during a term break) of key quotes from at least 3/4 main themes within each poem. you don't need to go into detail of explaining these quotes but as long as you write a mini 'note' / reminder of the significance of the quote + the technique associated with it, this can rlly help in the long run when it comes for revision and all your classmates are scrambling to memorise the poems.
also, DONT FORGET TO COMPARE!! this is a very easy mistake to make but as long as you remember to end your paragraphs with a mini 'conclusion' of how the two poems compare then you will receive AO4 marks that most people tend to miss out on. ALSO PLEASE REMEMBER THAT FOR THE ROMANTICS' SECTION YOU DO NOT NEED AO4. so many people on exam day discovered this and had to come up with a new structure hours before the exam because they thought they needed to compare the two. do not make this same mistake as it will save you so much time (even my classmates were panicking about this).
ALSO, on the student room if you search up practice comparison essays to do with the poems of the decade texts and unseen texts, there is one thread where someone writes what their class did which i used to practice how i wrote about unseen texts within timed conditions.
hope this all helps again and i wish you the best!!!
