Well done upon wining an appeal to CRGS, yours is the only success I have ever heard of to CRGS.
My middle son, for whom we lost an appeal, with an older brother already at CRGS, won one of the 4 new places created in yr 9 and did very well at the school. (Having created mayhem in a supposedly good comp for 2 years) Indeed his A level results were even better than those of his younger brother who started at the school in yr 7 at the same time as middle son.
I believe there are many boys who are very capable and who would benefit from the education on offer at CRGS (and indeed KEGS) who each year loose out simply because there are not enough selective places in north and mid-Essex. The current system fails to provide for the special needs of many academically able youngsters! Some of those youngsters, especially bright lads, never fulfil their potential and a few end up in bad places.
Time to climb down off my soap box now
