He is an expert in his field and is an extremely enthusiastic professor, not to mention pretty humorous as well.  Collective Behavior was easily one of the most enjoyable classes I have taken so far at the UW. Exams are difficult, but if you do the reading and understand the concepts you should be fine.","source_url":"https://www.ratemyprofessors.com/professor/1197389","quality_rating":5.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:49:20.501287+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTIwOTE3OTUy","source_instructor_id":"rmp:1197389","instructor_name":"Chaeyoon Lim","course_label":"SOC543","course_id":"SOC 543","course_uid":"course_060a4c992f0dc2ef8f3f277f","review_date":"2012-11-29 23:53:05 +0000 UTC","comment":"Great professor.","source_url":"https://www.ratemyprofessors.com/professor/1197389","quality_rating":5.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:49:20.501287+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTE3OTYyNDg0","source_instructor_id":"rmp:1197389","instructor_name":"Chaeyoon Lim","course_label":"SOC543","course_id":"SOC 543","course_uid":"course_060a4c992f0dc2ef8f3f277f","review_date":"2010-12-16 10:19:11 +0000 UTC","comment":"Collective Behavior - recommend to anyone, esp those with interest in social issues, welfare etc. Uses timely and provoking examples. Class focuses a lot of application of theory w/ current examples. Hard to get into and only teaches every so often. He clearly loves the subject and is excited about teaching. Put in hard work & you'll do well.","source_url":"https://www.ratemyprofessors.com/professor/1197389","quality_rating":5.0,"difficulty_rating":5.0}]
