Thanks Lidl 
He's pretty good at his public speaking and apparently his discursive and creative pieces were very good (the creative piece a somewhat dark short story about a serial killer
), so I'm not concerned. To give him his due, they really are all his own work with only guidance from his teacher and zero input from us. I've only heard descriptions from him about his work - never actually seen it.
Close reading was the area he struggled with in his Prelim - but I think that was partly to do with his scary teacher being an incredibly tough marker 
It'll be interesting to see how he gets on for his Higher: he has a new teacher after having had the same one for 4 years
. He seemed to like the new teacher for the couple of weeks he had her before the end of the summer term. She should be good though: she's the new HoD - and as the Headteacher is an English teacher by training, presuming she had a fair idea what she was looking for 
No idea how the school manages its budgets so that it doesn't expect pupils to buy their own text books. The Parent Council does contribute funds to two different special budgets: one, the Achievement Fund, which is available to ensure that all pupils have access to educational opportunities (at the discretion of the school to maintain confidentiality), so it funds some lunch time groups, trips to Open Days, access to DoE If required etc, and the other is a Purchasing Fund, for optional extras the various departments would like (they have to make a case for it). So it wouldn't include Business as Usual (so no text books
) but might include, say, special knives and display plates for Home Economics (used in competitions?) or costumes for the gymnastics team.
If they did want people to buy text books, I would imagine the Achievement Fund would get lots more requests
