A Level English Literature Essay help

Hi, I'm in Y13, I study the A spec, Othello, Gatsby and pre-1900s poetry, and I do paper 2B modern times, post 1945, Handmaid's, Feminine Gospels and Streetcar.
The way I'm currently writing is at the Top of Band 4. From what I gather my essay are usually lacking in terminology and sometimes context (that one is much less frequent).
My question is, does anyone have any advice how I could improve my essay writing, like how I could bring in terminology so that it sounds more organic, not like it is shoehorned in?
Also, any other general tips to improve essays? Sounding more assertive in my essays has helped me move up to an average of 21/25 in my responses. I am predicted an A* and really want to get that, but that means getting an average of 22/25 on each essay if last year's grade boundaries are anything to go by.
Thank you!

Hi, I think by 'terminology' it means the way your writing the essay, I would read a lot of scholars articles on the text and try learn how they write, what kind of words their using

Anything particular that I could look out for that looks like terminology? I know it seems odd that I'm getting high Band 4, but what I know of terminology is limited, I literally found out 'allusion' is a device last week. I have two teachers, yet somehow only one refers to my terminology as a bit of an issue while the other one thinks it's fine. Though one does teach me Othello and Gatsby and her issue usually is that when I talk about Othello my terminology is scarce and I don't always talk about stage craft. Sorry this is so long. My brain is trying to find a formula of sorts to follow so that I can improve, that might not be the best way to sound organic in the essays though😅.
