I am an undergraduate at a US college. I wanted to take a course in a specific area of my major so that I could do better research during the summer. I do not have the prerequisite courses but I have extensive industry experience in this area so they are much less relevant. The course instructor (A) was ok with allowing me. I tried to respectfully ask permission from the department undergraduate advisor (B) but he refused permission right away and wasn't interested in what I had to say.
In a last-ditch attempt to be able to take the course, I emailed a higher-ranking member ofprofessor (C) in the department explaining the issue and asking if she could help. This professor (C) forwarded my email to the original advisor B, who immediately sent me a nasty email saying that I don't dare ask someone else after I asked him.
While I can understand why the advisor reacted this way, why would a department member forward an email explaining a problem between a professor and student to the professor? I cannot wrap my head around it. Is this normal behavior for academic faculty?
