Academia can be one of the most vicious places about. There are plenty of insecure people out there trying to prove their worth through good grades and intelligent thoughts, and it can make for an unpleasant environment if you happen to be caught up in it all.

The more competitive the context, this worse this is, as u/Maleficent-Day4476 has recently found out. After her college professor congratulated her on her great exam results in front of the whole class, her predominantly male cohort began to tease her that she had succeeded thanks to her looks, and asking her boyfriend for help.
When the Redditor shared the behavior she was subjected to by her supervisor, the other woman insisted on notifying the head of department. It led to her facing even more animosity from her fellow students, but r/AmIthe*sshole were completely on her side.
