Mine also did Eduqas for English Language. A lot of the YouTube stuff is geared towards AQA.
The best advice I can give you is walk yourself and your DD through the past papers. They are all online, pull up the question paper, print it off if possible so she can section off when it says in lines 4-12 she draws a square bracket around those lines so she only looks at answers within those lines. Then open the mark scheme for the same paper.
Read the mark scheme, do not skip to the answers, look at the Assessment Objectives. Understand there are levels to the AOs.
Look at the first question, talk about what the answer would be, then look at the mark scheme. The mark scheme shows you exactly what they are looking for. Walk through each question together. Then for the next paper, see how well she does without help from you, she gives you the answer, you check the mark scheme.
Re the narrative. they are not expecting anything incredible, they are 15/16. What we did to prepare was descriptives down for people, weather and settings. Google words to describe rain or wind, then look at synonyms, you can't really prepare a full narrative but they are looking for use of language and punctuation.
Mine had descriptors for a park, a school playground and a beach. Both day and night, rain and sun, November and July. Contrast November on a UK beach to July. We took a lot from Stacey Reay on Youtube who won teacher of the year.
I think as an adult it is easier to see when it is all spelled out in the mark schemes. If you get chance read at least one examiner's report that talks about what people did well etc. Look at your DD's school book too and what she has been doing in class.
For English Lit, Mr Salles was the game changer plus the CGP revision book on the poems which my DC's school used in class as a teaching aid. Concentrate on form and structure, get that into any response on analysis. Salles is great for quotes plus AO3 for understanding that everything is a work of fiction, written to make the audience feel a particular way. The beginning and end of any poem or book is important.
We had Mr Salles book for Romeo and Juliet, in that he says every question can be relayed back to patriarchy. Juliet chooses to marry Romeo for agency, at the end of R&J Romeo kills Paris, marrying for love trumps an arranged marriage.
