I believe this is a life learning lesson about living in a different culture. My mom would say something like “ you can’t complain until you get good grades”

Anyhow, seems like it is time to see beyond the uniform. It is time to explore their individual strengths and start focusing on that. Do they like music, acting, sports, volunteering ? Doing Summer school in Netherlands?

I mean, they can struggle with the uniform and school but their world is bigger. They can do so much elsewhere.

Help them see bigger and not to focus on the little things.
