I live near Dorking. My dc actually go to The Ashcombe, but I know lots of people whose children go to Priory and they are very happy with it.
You're not considering Ashcombe at all? Those 2 school are quite a distance apart so not sure where you live!? Last year Priory was very popular and children in my village, Westcott, didn't get in - Priory is actually our nearest secondary.
