As a Modern Languages graduate, I think Latin is more important than many think. It does seem a shame to drop it without doing GCSE after 3 years of study, but if she is very good then hopefully she will retain the benefit. I can see the benefit after that in stopping Latin and getting on with subjects esp. languages she does want to take further. But it is certainly useful.
I think it might have been the word 'binning' that got my hackles up.
The thing about this thread is OP - or on the previous one - seemed all of a dither about her plans for financial reasons. That seemed to be why she began the discussion. So it seems quite apt for those of us with experience of the state sector to mention a lot is possible there. Of course it depends on the area. But I think OP - no question of checking back - did suggest her local state secondary was okay. And anyway, if the family is talking of moving, maybe she has a few more options which the family can afford.
OP has given me the impression anyway that she has some perhaps delusional idea (I have stated my bias!) that private is best, when it isn't necessarily so if a family is struggling to pay for it and there are many options, even for some subjects a bit of sharing of resources between sectors as a PP above has said. For senior pupils anyway. And considerable community resources in many places for things like music, drama and art, all subjects the OP regards as important, and rightly so.
I don't think a them and us thing between private and state ed parents is useful or indeed totally realistic. At the end of the day, we all just want the best for our children.
