Hi! I'm also doing m/j 9093 this year. I just found a helpful website for resources here:
http://eddistutorial.com/as-english-language.htmlAlso, you can look for "Sample Candidate Responses" just by adding 9093 with it on the search engine.
For me, the commentary (paper 1) is the most challenging, I have compiled some sample analysis (although they are of poems they help to understand identifying different figurative language, techniques, and effects); if you want that message me, make sure to specify that you want that.
I think for paper two, you have to do some research for solid points for (Q2) but the imaginative writing (Q1) depends on how much you read, and how you can employ those skills in your writing.
You must be careful though, for it can't be quite easy and require hard work and time. For basics, these videos might be helpful:

https://www.youtube.com/watch?v=3P_XeyPh2XY (Basic Figurative Language techniques)

You can also go through the syllabus:
https://www.cambridgeinternational.org/Images/329328-2019-syllabus.pdf and make sure you know the meaning of terms used in markscheme because there are a very few available candidate responses. Good Luck!
