I can tell you everything from experience.
My brother was 6 years old when he started this school. It is a total waste of money, paper and time. Your child's education is very important, so please invest in something worth it. My brother received so much work he received basically no childhood. They give papers that are not even actual paper, it is the same material of toilet paper. We also had very bad experience with teachers. Most of the teachers there are young and inexperienced and can barely speak proper english. They also do not teach the children, they force them to memorise their work.
Also the food provided in the school is terribly unhealthy, very unhealthy junk food, chocolate, chips, oily chicken legs, chicken nuggets. Also the teachers give really unreasonable punishments. My brother was given a detention for leaving out one word from his homework. My mother was called in from her meeting at her work to come to school to be yelled at by the teacher for not checking her son's homework, because her son didn't write one word. Then she had to drive all the way back to HongKong island to her job. We also had an incident where the teacher was threatening to slap my brother, because they are totally unproffesional.
Also the secondary students are very vulgar, they sit on people's cars outside their school and smoke.
Luckily when my brother turned 8 years old, we changed to Po Lun Kok Primary, and it is a better and happier environment.
