More than a hundred students at Lincoln University are being re-tested after suspicions they used AI to cheat. 

An entire post-graduate finance class is suspected of wrongdoing, with a threat of disciplinary action if they can't individually explain their workings in an in-person presentation involving coding and answering questions.

The university's Provost, Professor Chad Hewitt, explained there are some cases where they allow the use of AI - but in this case, students were expected to use their own brain. 

"The course has just identified a high number of suspected cases - as a consequence, the easiest thing to do is to bring the students in and ask them questions."
