A few days ago, my 10th grade English teacher (who we'll call Mrs N) gave us an extremely hard test that we as a class were unprepared for. Needless to say, the class did extremely poorly, with the average score being a 55%. The following day she proceeded to berate and blame my class for having done so poorly on the test, even though we had only spent about a week and a half on the material, and (at least I believe) that when a class does so poorly on a given test, it is the teacher's fault for making the test too hard. 

Over the weekend, I, while still being mad at her, decided to send her an angry email. I will put a copy of the email as the first comment, but essentially, it was very passive aggressive, blaming her for everything and insisting that not count the test as part of our grade. I sent this email from a throwaway email address not associated with my name, and signed it as being from the students of all of her gifted program classes. A thing to note however is that while I was the only one who wrote the email, the sentiments were shared by almost all the students.

Today in class, Mrs N confronted all of her classes by acting extremely disappointed. She threatened to punish the all of her students for this. Furthermore all of my fellow classmates, along with Mrs N, are mad at the person who did this, but I believe that my classmates are simply mad because they might get in trouble, but they agree with what I said.

So AITA? and AITA to my classmates or my teacher or both?
