He was extremely combative with students, sometimes spending entire class periods arguing with students during their in-class presentations.","source_url":"https://www.ratemyprofessors.com/professor/1522421","quality_rating":1.0,"difficulty_rating":2.0},{"observed_at":"2026-09-07 16:06:14.053692+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQyMjUwOTk3","source_instructor_id":"rmp:1522421","instructor_name":"Shamgar Gurevich","course_label":"MATH540","course_id":"MATH 540","course_uid":"course_edc3174bf073c9d7af51f678","review_date":"2025-12-15 01:38:22 +0000 UTC","comment":"He introduces the linear algebra from Categroy theory. He massivly uses ring theory, or natural isomorphism to introduces theorems in Linear Algebra. It's worth nothing to take this course to understand how to apply linear algebra on engineering. But it's very useful if you view Linear Algebra II as an introduction to math structure.

You will not learn anything; his course is organized extremely poorly with awful explanations and no standards for work. It's evident how little he cares. I guess one nice thing about his total lack of effort is that he will give you a good grade no matter what, but you won't learn a thing.","source_url":"https://www.ratemyprofessors.com/professor/1522421","quality_rating":1.0,"difficulty_rating":2.0}]
