Lectures were well organized & helpful. Not recorded, so attendance was necessary to learn the content well (but not required). Homeworks are difficult but interesting to work through for someone interested in the subject. Exams are easier than HWs.

Prof Bach made the course approachable. He was willing to explain the topic and answer questions, whichever is asked at class. He definitely made it less intimidating to learn.

He presents the material without any real clear direction, and half the time stands in front of what he just wrote, making note-taking a nightmare. The homeworks are impossible, but the exams tend to be a little easier and you can muddle your way through them.

He's a little old school and only lectures on a chalkboard, however, he tries to put up relevant material on the website. He's slow to grade, but overall, a very good professor who knows his stuff. He also writes his own fresh problem sets fresh every semester with novel problems and takes feedback actively for class ","source_url":"https://www.ratemyprofessors.com/professor/125529","quality_rating":5,"difficulty_rating":2},{"observed_at":"2026-09-07 16:40:46.468571+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM3MzY4MTQ3","source_instructor_id":"rmp:125529","instructor_name":"Eric Bach","course_label":"CS435","course_id":"COMPSCI/ECE/MATH 435","course_uid":"course_2e71825a82859020279c78b8","review_date":"2023-01-23 17:18:16 +0000 UTC","comment":"Extremely difficult professor, all of the material is presented at a ridiculously high level. A lot of the times I looked up alternative lectures. Homework is near impossible, and expects you to know terminology and material covered in CS240 (i.e. proof techniques), despite the fact that it's listed as optional.

He works strictly on a chalkboard, covers his work most the time, explains complex ideas in vague symbols, has confusing lectures, and assumes us to understand his proofs before he trails off.
