my son is a P.3 student transferred from APS this year. He told me that all the teachers, especially the school principal, are very kind in DPS.
Regarding the workload, he, in average, needs about 1.5 - 2 hours to complete the homework eveyday and I need to spend about 1.5 hour to study/review with him every night to prepare for dictation/test every week. So, I think the workload deems reasonable in HK standard even sometimes he mumbles about it.
Also, this school is able to encourage my son on reading (Both English and Chinese). My son, in average, reads 5 books per week without grumbling at all. Instead, he enjoys reading which I never expect before.
My son always tells me that he likes to study in this school very much. My wife and I both think our decision to let my son studies in here is the right choice.
