Something similar happened to me once. Coming up for our fourth year exams, our English teacher was going through everyone's record to make sure everyone had done all the required coursework.
She read the names out in the same order as the register. She skipped out my name, which I knew was a bad sign. After going through the whole class and telling people what they were missing, she says "Craig. You have massive gaps in your folio. Stay behind after class".
I stay behind and she starts telling me the pieces that are missing. I had done all of them. She asks me where they are and I told her they were in my book. She had graded them all too.
She opens her desk and lifts out everyone's book. She starts going through them and says "Your book isn't here, you'll need to do it all again".I looked down at her drawer and could see the cover of a book sticking out from underneath a bunch of paperwork. Not wanting to do two years worth of coursework again, I reach down and pick it up. She snaps "Don't go through my drawers" (Yes, I am aware of the innuendo) And I hand her the book and tell her it's mine.
She flicks through the book containing all the articles that had already been graded by her. She then tells me to go.
In my next class, some of the guys were taking the 🤬 out of me because of what happened. The next day, I was back in her English class. I raised my hand, and the 🤬 ignored me for nearly ten minutes. Eventually, she looked at me and said "What is it?"
I asked her for an apology. She was livid and tried to give me a punishment exercise. I told her I wasn't doing it as I hadn't done anything wrong. She sent me to the headteacher, who was actually okay. My headteacher asked me to do the punishment exercise and I told her that I wasn't doing it, and she could call my father if she wanted. She didn't, and I didn't have to do the punishment exercise.
Two years before that incident, another teacher tried to give me a punishment exercise because the chair I was sitting in broke and I fell to the floor. Again, I told this teacher (my french teacher) that I wasn't going to do it. Long story short, I got sent to the headteacher's office. She phoned my dad, who asked to speak to me. I told him what happened. He asked to speak to her and told her that he wouldn't make me do it.
My school was terrible. At least my Dad was reasonable.
