hi we are christian and my daughter too, we go to our church on Sat. and Sun. but I don't think there is a must this school to have the christian activities as chirldren go to school for learning and playing, unless it's a christian school.
this is an excellent question! for example their Primary English lesson, since they don't have lesson book and do modular material teaching, the school will be educating them about zombie (as I saw in project demonstration during open day), Halloween... etc etc.
