Please consider this option for your child :)
My youngest ds is at a fabulous independent school on a full bursary (we are very poor, sadly) and I can't tell you how much I worried about him going, and him being the poorest kid in the school, getting picked on for being poor, the school being too 'posh' for us etc. But he is having a wonderful time, simply wonderful, and we are all very very pleased with this choice.
He is pretty clever: he had to pass exams and an interview with the head to be considered for this bursary; I mean, he had to fulfill two separate conditions for the bursary: - he had to pass the exams pretty well, and he had to come from a household with a low income. But he's not the cleverest kid in his class, he's ok, but not outstanding. Plus he's one of the poorest, with some truly wealthy kids there, but, nonetheless, he loves his school, has made masses of friends, and the education he's getting is simply wonderful.
I only considered this option for my ds because a friend suggested it; she only suggested it because her son was there already; she is poor too; her son loved the school and so did she, so I considered it for my ds; now he loves it too.
Go for it is my advice!
