The school starts in y7, so it’s a totally new cohort. If girls come from the same school then they are put in different forms, so they have a fresh start. They are taught within their forms for everything in y7, so they really bond, although they’re obv free to mix in breaks/lunch/clubs.
This year the girls have two full sessions of sport - lots of running along with football/netball etc. My dd feels her fitness has improved through it and she’s found she’s good at some athletic skills she hasn’t tried before. There are sports clubs at different levels at lunchtime - some you do a trial for and some anyone can attend.
I know that some girls are taken to compete in matches/races etc, but that hasn’t involved my dd so I can’t comment.
Homework - there was one week early on where my dd had let it stack up and panicked, but overall it’s very manageable (less than in primary!) and almost everything is due for the same day the following week, so if you have evening activities it makes it easy to work around. The girls are expected to manage homework themselves and I believe my dd has risen to the challenge of that. I know recently lots hadn’t done a Latin homework, my dd had so she and the ones who had did extension work, while the rest did the homework in class. I love that it’s more ‘natural consequences’ and ‘you’ve let yourself down a little’ rather than punishments.
Instruments - again there’s a huge range and at all levels. From grade 8/diploma to fun ensembles for beginners. There are lots of choirs etc too.
Bullying - I haven’t heard of any, but again the girls are spoken to respectfully and asked to discuss what’s happening and why. Counselling is freely available in school and there is a wellness hub that lots of the girls go to in their free time or if they need support.
I think that’s all your questions and I hope it helps.
