More concerning, though, is how discouraging he is after poor exam scores; he tells students to reconsider the course or even their major. That kind of response is demotivating and inappropriate/unethical from a professor.","source_url":"https://www.ratemyprofessors.com/professor/1029779","quality_rating":1.0,"difficulty_rating":5.0},{"observed_at":"2026-09-07 16:06:34.601176+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQyNjQ5NDA0","source_instructor_id":"rmp:1029779","instructor_name":"Sean Paul","course_label":"MATH321","course_id":"MATH 321","course_uid":"course_cd8a47c5c8808c1cc3427d87","review_date":"2026-02-26 23:36:49 +0000 UTC","comment":"Sean none of us took math 340 like literally 5 of us maybe the rest didnt so yeah\n","source_url":"https://www.ratemyprofessors.com/professor/1029779","quality_rating":1.0,"difficulty_rating":5.0},{"observed_at":"2026-09-07 16:06:34.601176+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQyNjMwMzkw","source_instructor_id":"rmp:1029779","instructor_name":"Sean Paul","course_label":"MATH321","course_id":"MATH 321","course_uid":"course_cd8a47c5c8808c1cc3427d87","review_date":"2026-02-20 19:59:04 +0000 UTC","comment":"Sean Paul's a chaotic teacher. His lecture material often differs from the textbook, and he fails to articulate his expectations. This, coupled with sudden office hour cancellations and random email response times, makes him hard to work with. While he knows and cares about what he's teaching, a little organization would go a long way for his class","source_url":"https://www.ratemyprofessors.com/professor/1029779","quality_rating":2.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:06:34.601176+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQyNjE3MDQz","source_instructor_id":"rmp:1029779","instructor_name":"Sean Paul","course_label":"MATH321","course_id":"MATH 321","course_uid":"course_cd8a47c5c8808c1cc3427d87","review_date":"2026-02-16 23:19:07 +0000 UTC","comment":"day one of class he holds up fabians textbook and says \"who here has read this front to back?\" and half of the class who is retaking raised their hand. then he said \"forget everything you thought you knew because its all wrong!\" and the whole class erupted in a jolly cheer. and we lived happily ever after. the end.","source_url":"https://www.ratemyprofessors.com/professor/1029779","quality_rating":5.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:05:40.791944+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2MzQ5MzI1","source_instructor_id":"rmp:2616322","instructor_name":"Shubin Fu","course_label":"MATH321","course_id":"MATH 321","course_uid":"course_cd8a47c5c8808c1cc3427d87","review_date":"2022-05-16 16:21:20 +0000 UTC","comment":"I don't think you'll ever find a professor who cares more about their students than Fu.

My one big issue with him is his rigidity in homework due dates. I had to miss class due to COVID and family issues for a total of almost 3 weeks. He refused to grant me any leeway or ability to make up missed HW. HW is due at a set time, no exceptions, no excuses. Never had a professor so rigid and uncompromising with HW ever","source_url":"https://www.ratemyprofessors.com/professor/2826174","quality_rating":2.0,"difficulty_rating":3.0}]
