Thank you for your comments.
I was just hoping about some new info about the Perm state ballet school, as the last ones were in 2012, 10 years ago. I know that the UK students were in Perm since than, maybe somebody will come with comments.
Answer for SillySally: yes, my daughter got two offers. I cannot say yet about the differences but for sure, Perm is a classical education, probably a bit old-fashioned, while BIBS is a private, small and already known positively.
My daughter tried UKs big schools. Without luck.
