I'm sure she will thank you when she is 57 and finally lands a job in a school in England- cleaning toilets.
Dominic, instead of posting insulting things, why don't you tell us how much experience you have (directly, not anecdotally) with the Polish and UK educational systems? I'm not talking about tutoring people from such schools.
The good international schools here pay more than UK schools pay but the cost of living here is lower than the UK average and a lot lower than cities such as London, Bristol, Southampton, etc.
I think it's worth being fair and saying that the elite schools might not take her - but there are endless second-tier schools that would bite her hand off.
