May I ask anyone of your child been to the Hong Lok Yuen International school, or any of you know about this school, e.g. the study environment good or not, teachers quality, student–teacher ratio, the school system and so on.
Just take a good look of the school website, it actually has quite detail informations about the school and would give you a very good insight into the school.
Then call the school and arrange for a school tour, you will be able to see the school, talk to the staff and observe the students in order to form your own judgement.
It's always nice to hear from the others previous experience(not even one comment about it) plus take a look to the school website, school tour and speak to the current staffs(Already did).
