True, the wording of the original post could have been better, but essentially op is asking opinions about 3 schools, if she had written 'could I please have opinions on CH, Reeds and Gordons and what their bursary policies are' then nobody would have the information to flame her as they wouldn't even know what the state option was.
So, shes 'guilty' of being too open with her information. Perhaps people can look beyond this 'too much information' and give opinions on the schools she would choose to send her ds to if he is successful rather than judging the reasons for making this choice.
In the end, you only know that her state option is because she slipped up and toldyou. You only know the other difficulties with her ex because she told you. This doesn't equate to a sense of entitlement, smoke screens or anything else - it equates to being too free on a forum with information.
So - opinions on schools
Gordons - I've known a lot of youngsters go through this school, they either seem to love it or hate it. Until recently it seemed to have an overiding 'miltary' ethos (parades etc ) and the girls boarding houses in particular had quite bad bullying problems if they didn't fit in with the group quickly.
CH - very competitive, personal experience they back off when there is obvious disharmony between parents about a child attending there (was told that both parents MUST sign the admission and bursary forms)
Reeds - getting increasingly difficult as many who get rejected from Royal Grammar School in Guildford tend to then apply for Reeds. Their new, shiny very expensive 'Futuretech' design centre is attracting a lot of attention. They do work a lot with local primary and secondary schools.
Their bursary policy is foundation bursary only; something like the boy must have lost the support of one parent for a variety of reason, have a particularly difficult home life etc - these bursaries are for day and boarding places and stem from Reeds originally being founded as an orphanage.
The bursary process is difficult, you have to do full financial disclosure and a statement in support of application, reference from current headmaster and the parent has to be interviewed in addition to the child passing the entrance exams and boarding assessment if applying for a boarding place.
Currently going through the Reeds process for a day place.
All of these schools will expect a parent to be able to contribute according to their means, so its by no means free - for example Reeds do say that they work on at least a 25% parental contribution so with fees of £21, 000 and you have to factor in uniform and other extras, the bursary will not cover all of this except in exceptional circumstances.
Theres no reason for OP not to give it a go, but do weigh up the commitment and check out other alternatives as it does depend on who else is applying and how far the bursary pot has to be divided.
