I find it quite sad on this forum every year to see parents posting that their child has been successful in an entrance exam, has 'set their heart' on School X and School X alone, and they can't afford the fees because they had been hoping for some kind of financial assistance which they had failed to secure.
Obviously you don't know ahead of time if a child is likely to be one of the few lucky ones, so I think it is really important not to let a child fall in love with a school you know you have only a tiny chance of being able to afford. Bursaries are very hard to get and are supposed to be for cases of genuine hardship+very bright child only; and scholarships are often little more than honorary titles with a small cash prize thrown in. There needs to be a back-up, affordable (state) plan which is sold to the child as just as good, to avoid heartbreaking scenes of still very young people being told they have passed an exam but can't go to a particular school, and there is nowhere else anywhere near as good. Phrases such as 'school of his/her dreams', 'has his/her heart set on x school' surely really have no place in this game - parents have to be the grown-ups here and manage expectations accordingly - as in 'it would be a lovely surprise if we got some help to send you to School X, but School Y is lovely too so let's see what happens'.
Just my view, but it is quite a strongly held one.
