I think the academic standard especially in Chinese and Enghish is good. After 6 year primary education, the children can easily get used to Enghlish Secondary School.
Chinese and General Studies: taught by Mandarin
Maths: English Maths not Chinese
Science: taughty in English
English subject: they will teach one year higher
My daugther has been studied there for one year then she can speak fluent Mandarin
Small size class teaching: 1 teacher to 22 students
They have provided tutorial class after school for students.
But the Tak Ching Secondary school is not English.
