My quantum mechanics exam

Hi, I will try to write about my exam in quantum mechanics. He was four days ago. In the ticket was two question:1)momentum operator and coordinates 2) polyhydric molecule and method Fermi. I knew both questions.I was approached by a teacher and he began to ask. He ask me a lot of question, and they wasn't very hard for me. But in the end he put me a low mark and I think that it is unfair.
