If you are indeed looking for information about boarding schools in Britaiin, then try searching under that. Any guidelines or help should be found in Off-Topic as it is nothing to do with schools in Switzerland.

What did she find hard about it? I'm wondering what to expect from the Swiss school system, since my daughters probably will have to go to Swiss school. Sorry I don't know anything about British boarding schools.

She did well in primary school, but needed more help with homework than I was able to provide once she got to middle school. My German is not bad, but not good enough to easily help with homework. She has problems with concentration and attention and organizing herself. I finally found a very good tutor that I could afford, but it happened too late to get her grades up enough to make it into the next school (she is still going to try the entrance exam but they don't let many through). She actually loves school and wants to continue going to school. She is only 15 and has no idea what she wants to do for a career and isn't ready for an apprenticeship, so I'm looking for affordable alternatives. Private school is very expensive here.
