While the rise of AI is helping education in many ways, it is hindering in others. After giving an exam, I used to provide the opportunity for students to make up some points by revisiting what they got wrong and writing about what went wrong and how to fix it. Last year, it became blatantly obvious that the majority of the class was using AI to complete this, thus defeating the objective. Since I think there is great value in revisiting mistakes, this year I administered an oral exam to make up points. Students knew that I could ask anything related to the exam topics. In this talk, we will describe the experience and what we learned in the process, from student attitudes to the administrative burden.
