The main boarding accommodation is in the main school building above the reception. How old is your son? There are very few non-6th formers who board, so it is a small community. It would also appear that the majority of students are from the same geographical region (HK), so if you're from elsewhere you may be in a small minority.
My boy recently received an offer from Warwick School for a full boarding. Any comment appreciated. Also, we cannot find the photos of the boarding school. Do anyone have some photos showing the boarding areas?
