Who was the worst teacher you ever had, and why?

[Tech]

The number of worst teachers/professors I've had is significantly much larger in magnitude than the number of what I would consider decent teachers.


I've had only one really really good teacher in my life and that was my father. Other than that, my high school bio/chem/psych teacher was a nice person and only my calc 1 teacher in community college at least was fair, unbiased, and knew what he was doing.


Since University I have had almost none


Call me negative, antisocial, whatever.


Until someone can actually prove to me that they are a decent teacher/professor, you can't say that I am wrong.
