I've got two daughters at the school, both doing really well. Mine are in Y11 and Y8 now. I agree the open events tend to be a bit underwhelming, partly I think because the school is so sprawling and hard to cover efficiently when there are hundreds of visitors all at once. And yes, they just get all the Y8s in to 'guide' without a lot of prep!
DD1 hasn't had many trips - it seemed that it all disappeared with Covid and is only really just coming back properly. No language trip offered for her year. She did do a couple of nights' camping run by the PE department, and her DofE bronze expedition (again, mostly organised and supported by the PE teachers - they are very committed and active). She's off to Iceland in a few weeks for a Geography trip, which makes up for it a bit. DD2 is going to Barcelona next summer (they were given the option of that or Paris).
Teaching has generally been good, staffing seems fairly stable. DD1 has had excellent Maths teachers, and has gone from being fairly middling in primary to very confident now, on track hopefully for an 8 or better at GCSE. Science has been somewhat variable (again I think very Covid-hit in her first couple of years, not much opportunity for practicals etc), but she seems to be enjoying it more now.
DD2 is enjoying the extra-curricular activities - last year she did LAMDA Grade 4 via the drama club, and also debating, tennis, and trampolining. This year so far she's signed up for the school musical production and netball club.
They both have nice groups of friends, go every day without (much!) complaint, and seem happy there.
