In the 4 years up to his Nat 5s, in English ds studied that I know of: Robert Louis Stevenson (Kidnapped); Shakespeare (A Misummer's Night Dream, Two Gentlemen of Verona, Macbeth and at least one sonnet); Steinbeck (Of Mice and Men); Harper Lee (To Kill A Mockingbird); various Carol Ann Duffy and Norman MacCaig poems; Ken Kesey (One Flew Over the Cuckoo's Nest); a bit of Beowulf; some Dickens (not sure which one and it might just have been peripheral to one of the Carol Ann Duffy poems)....and probably some other authors that he didn't mention.
No idea yet what he's studying this year for his Higher as he refuses to tell me (I'll have to wait until he starts talking to me about what he finds interesting about the texts...) although I suspect Arthur Miller might feature. I'm hoping he'll be studying Hamlet (I love Hamlet
).
I'm very happy with the range of what he's studied/studying and think it compares favourably with what I studied all those many
) years ago for my O Grade/Higher (English was my strongest subject and I won the English prize by a country mile and am very much my English-teacher-mother's daughter
)
Now whether that was thanks to his scarily intense teacher or the curriculum, I don't know 
Nowadays they have to do one bit that I didn't have to do but which I think is a good addition as it's a worthwhile skill (although for some kids it's a real challenge for them), which is the public speaking element.
Like others on this thread, I'm unhappy at the apparent constriction of choices prior to Highers. Ds is fortunate that he is at a school that allows 8 Nat 5s for those that are capable, which means that he had a full choice for his 5 Highers.
I know when I sat my O Grades (8 too), I found it difficult to narrow down as I wasn't sure what I wanted to do and liked both Arts and Sciences - so quite deliberately chose 3 Arts (English, French, Latin) and 3 Sciences (Maths, Physics, Chemistry) for my Highers (but I acknowledge that 6 Highers is unusual for state schools now)
I do fear that the strength of the Scottish broad-based education is being damaged with so many schools restricting choice. I understand that some of the thinking was increasing the level of the Nat 5 so that the jump to Higher wasn't so pronounced - but how do some schools still seem to manage it but not others?
