Preparation definitely helps me as a student. > Mistakes erode the kids' trust in you. In addition to this, I often find myself trying to digest concepts broadly because my mind is lackluster with the mechanical side of calculations. When a professor makes a mistake, I occasionally have to revert an already imperfect record (with or without notes) and adjust my conceptual framework. Just an anecdote about why I personally suffer from poor teacher preparedness as a student.
