I am finishing up my 3rd class with him and it's clear he really cares about his students. He is always available for questions and will often work through things with you. His exams are hard but if you engage you'll succeed. Curves the class so that you pass if you tried at all.

My major complaint is he writes exams that are way too long. He does take that into account and chooses exam times/locations that allow for students to work late, but midterms and finals take most people 2.5-3 hours.","source_url":"https://www.ratemyprofessors.com/professor/2745372","quality_rating":5.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:20:38.272258+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTI3NTM4ODYz","source_instructor_id":"rmp:1636591","instructor_name":"Mark Etzel","course_label":"FOODSCI440","course_id":"FOODSCI 440","course_uid":"course_f7010d6b7c027df8440eece9","review_date":"2016-12-16 21:49:53 +0000 UTC","comment":"Super clear lectures.
