I was at secondary school in the late 80s and it was not in the UK (Australia) so hard to make a direct comparison. I was pretty bright and did really well at school. But now I have a dd who is in year 9 at an independent school (not that this makes much difference I don’t think) and it seems to me that a lot of the work - maths, science and English in particular - is of quite a high standard - stuff I don’t think I did until much later.
