Anna - I'm sure you have misunderstood re Latin. In my DD's case each class alternated between going to Kings for their Latin lessons and doing the lessons at CGS. They swapped over each term but each class had equal time with each option. I would be amazed if they had now changed this.
I am staggered that you got the impression that there are no extracurricular activities or competitive sport played - that is definitely not the case. In fact DD has asked to give you the facts on this below:
Coombe takes part in competitions in netball, rounders, cross country, volleyball, football, badminton, tennis and athletics and there are extra curricular clubs in all of these and more. There are extra curricular clubs in music, languages, debating and literature among others. The competive sports teams actually perform very well and my year came first in the netball league, second in the borough rounders. We also compete in the Surrey Schools Tennis (we are the only state school to do so) and the year ten doubles team came second in this. The Coombe music department is also very high achieving and I am part of the chamber choir and the cast of Joseph and the Technicolour Dreamcoat, playing the part of the narrator. I hope you didn't have too much of a bad experience at the open evening as I sang a solo in the presentation !
Back to Mum now! DD also tells me the school makes a big effort to make sure help is easily available if needed. Dedicated pastoral care staff and counsellors are always available to them on a drop in basis and the head of year is always available for girls to talk over any problems. We have found the school has always responded promptly and helpfully when we have had any issues
Sorry for the long essay but hope it is helpful!
