By the way, there are also host families in Singapore, where parents are not in Singapore but children are studying in Singapore. It cannot be said that all students have poor grades, but without their parents around, if they are not very strong in their studies, their grades will fall behind a lot, especially for children in their youth, which will be more complicated. When I attended the school parent teacher conference six months ago, I met a classmate of a chipmunk who was in the same grade but from a different class. She was an Asian girl who looked like she was sixteen or seventeen years old at first glance, dressed, dressed, and applied makeup like this. To put it bluntly, this style is basically the norm on Japanese streets. So it's not just about English. If possible, it's better to study with your child, at least with one parent accompanying you. Otherwise, teenagers will not only have English problems, but also have the opportunity to talk about this aspect.
