@Bea822 Right, the best thing you can do right now is look at the mark scheme, understand what gets marks because it comes under certain categories. I have said this before under a lot of different user names. This is a game, you have to know what gets you points. The mark scheme has the point information. You hit all categories they have to give you those points. If you have a printer it helps to print off the relevant pages. Here are all the past papers

On the left hand side choose "exam series" just means which year. I have picked 2018 paper 1 mark scheme which covers Shakespeare and 19th Century text which your son picks A Christmas Carol. (Macbeth is also in this mark scheme but I will do ACC because that is one my children studied)

Look at page 6, this might horrify you but your son should have been told all of this in school. Print that off. Then look at page 18 which shows the ACC question and see it listed out under each AO category. It should now make sense what they are looking for. Do the same with the other mark schemes for paper 1, you can narrow it down by mark schemes only. Obviously you can do this for paper 2 as well for whatever they are doing on that one. The question papers will show what extract or poem was used.
AO3 is context, when was it written? ACC was just after a government report was commissioned to look into the living conditions of the working poor. Dickens's father was put in a debtor's prison. The people this book is aimed at are the rich, the factory owners, employers of people, Scrooge has but one employee, he changes his life with a pay rise, a tiny one to him but life changing to Bob as TT lives. Fezziwig treats his staff well, opens the door to everyone for the party "In came the boy from over the way, who was suspected of not having board enough from his master; trying to hide himself behind the girl from next door but one, who was proved to have had her ears pulled by her mistress" both are mistreated by their employers. Scrooge has a generous employer in contrast and this sets an example for the reader. This is a work of fiction, contrived characters to make the reader feel a particular way. Reference the reader/audience.
Don't forget half term for studying for exams after that whatever they may be. There is a whole week. Quotes, he doesn't need the whole quote just bits of it that he can drop into sentences ie from above that the boy is mistreated and that he doesn't "have enough board" and that the girl has her "ears pulled" by her mistress. I hope that helps in some way. I loved English.
