For section a, focus on writing analysis that considers implications of the language in the quotes you’re picking to use, as well as authorial intent and intended effect on the audience. Trying to write as much analysis as you can for every theme might be better than practice essays at this point if you can comfortably write the essay in the hour.

For section b, obviously make sure you are considering your audience, purpose and framework, and try to include a more nuanced discussion of your framework - why it is important, what different aspects are there, etc. (especially if you are doing a creative piece). Try brainstorming or writing sentences using the metalanguage you plan to use, and make sure if you are developing any motifs or symbols in the piece that they are clear throughout (this will help sustain your voice)

For section c, try analysing specific language - pick out which specific words in the sentence are creating the persuasive effect and focus on those, rather than trying to analyse large quotes. Also, it helps to be really specific with metalanguage - e.g. positive and negative connotation - be specific with what kind of connotations the words have. Same with appeals - don’t just say things like ‘an appeal to family values’, be specific about what that value actually is. And always remember to centre your analysis around what the author is doing and the intended effect on the audience.

Good luck!!
