The UCAS advice is genuinely good, and sets the landscape for unis.
I won’t give specific advice, because we don’t do arts courses so what we look for is a bit different (we have an arts school but they do all their own stuff) but in general… Well, absolute most important thing is, there are more terrible personal statements than there are excellent one. I’m not saying be average, but be thoughtful.
Experience and a personal engagement with the subject/course is generally what stands out, real examples to make the point, an idea of the thought process that led her here, and where she wants to go and how the course progresses that.
And remember that they have her grades and her portfolio so don’t rehash that much- they have that already in a better format, you can refer to it but don’t repeat it. Amazing how many people basically list their A levels, you don’t have space and even if you did it’d be rubbish
And if it looks like a cliche, change it. They want what inspires her and what makes her a good student, not a motiviational poster. No lists of things she’s done, it’s got to have context, no “I did the duke of edinburgh and that proves I am a top dude”, you want “I gained this when I did X” or “Doing X helped me to figure out why I want to do this thing”, that sort of thing.
And definitely mention about her need for more cock.
