Might be time to retire ngl. Exam Qs worded poorly. Graded on a curve (usually boosts score though bc almost everyone does terribly). Good luck with this one. ",

He also said certain topics wouldn't be on the exam, but they were, which made studying frustrating. Overall, not an easy class and hard to understand the material.",

However, the lack of slides, frequent tangents, and lack of drawing trees made this one of the most stressful classes I have ever taken.
