A-Level Fine Art Contextual Study

Hi, I'm currently writing my essay and frankly I'm just lost on the point I'm supposed to be making.
In my head I am writing this essay as a response to my component 1 sketchbook and what I explored in that sketchbook but if thats the case why am I writing it because surely the fact its all documented in my sketchbook, defeats the purpose of composing a written representation because it's not like i haven't got any writing in said sketchbook.
I don't know if anyone can understand what I'm trying to say but any help would be much appreciated!

Hi! I study A level fine art (Edexcel), what exam board do you do?
If you're talking about the personal project, what my teacher told me is basically just copy whatever is in your sketchbook into the essay, so basically it shows your journey of how you studied the artists and made artists responses and did other observational studies or other stuff you did in your sketchbook, and how all that led to developing your final piece (the conclusion)
Also make sure to add extra research into art movements, artists etc, basically make it more detailed than what's in your sketchbook. So like analyse say an artists artwork in depth, if that makes sense.
For the conclusion, talk about which bit in your final piece symbolises what, how that links to the artists, your theme etc
Sorry if that was poorly explained, english isn't my first language ))

I also do Edexcel. The way my teacher had explained it was:
Do all sketchbook work. Then look at your work and find a theme relevant to your coursework. Then write an essay where you research that theme, so I just got very confused. But this was really helpful tysm!!
