creative writing (URGENT)

i have my KCS sixth form exam in a week and its either gona be transactional or creative.
For transactional im just practicing but for creative i dont hv time so i was just gona pre-write some descriptive paragraphs and learn them. ATM i hv one on happiness, sadness, anxiety, a bad smell, a good smell, silence, a mysterious character, an animal, sunset, night sky, rain, a city.
My question is r there any other good things i should learn smth that’s versatile so i can fit into my writing no matter what question i get.
ALSO IM SO BAD AT descriptive writing does anyone have some paragraphs i can borrow or know a website that i can use. chatgpt is so ****
