His proofs in class were identical to the ones in the book. His lectures were nothing special. Just utter meh. If you ask him questions outside of the scope of the course, he doesn't know unless it's analysis related",

The exam was confusing, with problems chosen from textbook in a broad range. There are no correct answers provided. His lecture is super boring, making me lose my interest.",

Wasn't great at responding to questions; they often didn't look up from writing on the board and would cite previous results without much explanation. Grading was fair.  They basically told us what material was on exams. Attendance not required, but many examples from lecture showed up verbatim on exams.",
