"From what I read, it sounds entirely rubbish to me.
The best rthing would be to avoid that entire school and its system!
Who really needs that kind of crappy training centres?"

Turnoi, English please; 'avoid that entire school'? Why not avoid just parts of it? 'that kind of crappy training centres'? surely 'centre'? or 'these', or 'those', or 'this'.

Best regards,
Ian
