Teacher acted like a dick but it’s fairly easy to get a 98% on the final and get a C. Anyone who has taken a class in a standard us school and given a shit about their grade will recognize that they are typically also graded on the other tests, homework, class participation, quizzes, projects, etc.

Might also explain why the teacher was kind of a dick. Maybe anon was the pain in the ass student that clearly had the intelligence to easily pass the class but rarely paid attention, never did homework, was often disrespectful, etc and then was shocked when the educator wasn’t willing to work with them.
