I am delighted to inform you that xxxxxxx performed extremely well in her 11+ entrance exam for City of London School for Girls, and we are very pleased to offer her an interview here at City. We hope this is good news for you and xxxxxxx!
We had an extremely high number of applicants to City this year – just over 750 girls from a wide variety of schools. xxxxxxx, many congratulations. You should be extremely proud of your efforts so far – we are interviewing roughly 300 girls and we have sadly had to let hundreds of brilliant applicants know that they have not been selected for the final stage of the process. We do encourage you to empathise with any disappointed girls you may know of or who are in your class.
So, going by that, there are about
850 applications or so now a days
About half are selected for interview (350/750 in 2017 ) -- maybe 400 now?
75 get a place
