By the way, one AMAZING Youtuber for Macbeth is Mark Birch.
I saw his analysis for Macbeth a few months ago and it was very in-depth as well as perceptive. I urge your daughter to try him, because YouTubers are free after all
I’m pretty sure he also does a revision guide (“15 key quotations”, of which he bases his videos on- there’s the full revision guide but he doesn’t base his videos on that). It’s your daughters choice if she likes his Macbeth content and therefore wants to buy the “Macbeth 15 key quotations” guide. I haven’t bought it therefore can’t recommend it, but I just know he based his videos on that guide
