Teacher stressed about work?

Hi community,

I'm a 15-year-old male and in 10th grade at a high school. I was a good student until eighth grade. Now I'm a 2.7 student, making me one of the worst in the class.

Last week we wrote three papers. On Wednesday was the French paper. I'm okay with French, but I couldn't do well with that topic. During the paper, even though the teacher had my eyes on me, I took my phone and put it on the table. We had to write an essay.

ChatGPT did that for me. My essay was so rude that I couldn't understand anything, but I had no choice. I copied everything down. And I didn't get caught.

Today I had French, and she marked the work, which she will return on Wednesday. The teacher called me in at the end of the lesson. She kept asking me if I'd cheated and if I had a smartwatch or something. I firmly told her that I'd spent a week and a half memorizing the entire text. She was suspicious, but I tried to convince her. She said she'd looked it up and that ChatGPT gave a similar result. Because of this, I even asked her if memorizing was now forbidden. At least I knew what I was supposed to discuss.

Today, we had to take books from her to present them. My backpack and my group's were full. She yelled at me to take the three books. I was going on a field trip and told her. The stupid girl wouldn't listen. The other student in my group and I just left the room and went to the next class. I respect all teachers, but not someone like that.

Guys, what should I do on Wednesday? What should I do A) about work and B) about the books?

I'm asking for help. Helpful criticism is also welcome.

Thank you for taking your time.
