Got a little bit of feedback from ds today about his new timetable - only because I had to pick him up and take him to a 3D imaging appointment (he's been part of a longitudinal study since he was 3 months old, imaging their faces to help understand facial growth) so he was trapped in the car with me and had to talk 
He's in the Maths class he wants to be, which was his main concern, has a new Chemistry teacher which he's a bit
about as he liked his old one (but she has said he's welcome to go back to her at any time if he's struggling with anything/needs additional explanation), new Physics teacher which he's ok about, the Geography teacher he expected and doesn't know who he's getting for English. He's supposed to find out tomorrow but he's away doing a Glasgow School's Adventure Race all day - apparently the very intense teacher he's had since S1 is apparently not taking any Higher classes this year.
No complaints from his Computing Science friends (who are taking it on to Higher) about the Nat 5 - I asked specifically. He said they did have concerns about bits of the SQA curriculum and some inconsistencies in marking (eg when the right answer can be as simple as "mouse" yet the answer to "what device do you use to display information to a large number of people?" is not "projector" wrong but "data projector"
) but not the exam itself.
