When I was a freshman, I did take classes with domestic children and teachers from New Zealand Business School, but it was not a language class, but a professional class! Besides, it's clearly written in the contract. How can this parent be said to be a language class when he is taking a public course in business?
Moreover, it is also the requirement of our parents that freshmen attend classes with the children in the preparatory class. Otherwise, what if the child is a freshman at the University of New Zealand without friends and the language is not suitable?
What's your child's name, this parent? Have you talked to NTU's teacher?
