My teacher uses CHATGPT TO MAKE MY EXAMS??????

So... I course in Photography right??????? I got two professionals teaching me, and one is kind, the other one is rude T_T... Let's call the rude one Mr.A cuz why not? So... The day of the exam comes, and Mr.A hands out the papers to us, nothing weird, right? Till you look at the exercises and they make 0 SENSE? I wasn't the only one struggling, mind you!! I ended up giving in an exam that I WINGED, WHICH HAD NEVER HAPPENED BEFORE SINCE THE START OF H.I.G.H SCHOOOOOOOL? And at the end of the exam, one of the students asks why it was so confusing, and Mr.A is just like, "Oh, ChatGPT made this exam lol I just wrote in a prompt to make for it to make me an exam that includes the topics you all should have studied for" like what?? YOU'RE A TEACHER. WHY ARE YOU USING AI TO TEACH US
