Are there any parents of students in ATS that can enlighten me on the work/pressure load of the school? Example spelling, ting Xie, amount of homework etc.

I heard that in some SAP schools, instructions or announcements to parents are in Chinese?
Now that P1 registration is nearing, wondering whether we shd consider ATS as we r under 1km. The other option is Amk primary which has plenty of seats. But the key consideration is whether the SAP environment in Aitong is suitable. Really appreciate any sharing. Thanks!
