Fascinating reading this as I was at HS about 25 years ago and it sounds like a completely different school which is just as well as I hated it, couldn't get away from the place quick enough and went on to do A-levels elsewhere!
There was no rowing, no real after-school clubs (just a couple of choirs and sports teams at lunchtime), none of the enhanced facilities... It prided itself on being academic and sporty - which was bad news for me as I was academic but into science and not classics (couldn't even do separate science o-levels there in those days) and rubbish at sport. Science stuff was very looked down on.
Boarding was dreary - they had 'activities' at the weekend, but they were just for an hour each day when they kicked you out of the boarding house to be bored elsewhere. Food was rubbish. No TV other than an hour to watch top of the pops and a couple of programmes after it (unless you were one of the younger ones, they sent the 11 year olds to bed at 7.45!!!), there were rotas on the number of baths you could have (3 a week) and hairwashes (one every 2 weeks because the hair clogged up the drains apparently
).
Housemistress in my house had been there since the late 50s and didn't see why there was any need to change anything
so it was like living in a timewarp - even in the house bookshelf library there were old copies of the London Illustrated that dated from the turn of the century - along with a few more books, nothing less than 10 years old - no point buying books when the bookshelf was full.
Several of the teachers could be real bullies and seemed to enjoy their reputation for being a dragon. They also missed that my sis was dyslexic for 4 years so she needed extra lessons that were charged for in those days (and that support teacher was the only nice teacher in the place to my sis, the others were very dismissive of her keeping the average exam scores down and wrongly assumed that because she was my sis (and I was at top of the class most of the time) she wasn't bothering to work. In fact, she was the one working flat out and I was able to cruise initially because I'd been to a good school before and was repeating the first couple of years work)
headmistress changed while I was there - we went from being Dunn's nuns to Tuckers f**kers
No ideal what the current head is called to know what the girls are now!
Sorry OP, this has turned into a bit of a rant, usually try to stick the place in the dark recesses of my memory; but glad to hear that things are a bit better now
