Quiet, monotone, and mumbles. See if you can attend another prof's lectures, or read the textbook every week. Sample problems are a must, so again, see if you can find another prof's videos. Exams are fine if you know the material and practice. Labs can be hard, so be ready. This semester (25F) they had an AI mark everything, which sucked a lot.

Prof Eicchorn is a very soft spoken professor which makes it harder to understand him in the lectures, so I would suggest sitting at the front , mumbles frequently which makes it near impossible to hear anything, and don't go to the lectures, just look at the textbook if you want to pass. He is approachable after class however if u have questions

Very respectful and sweet, but he is soft spoken and mumbles a lot. Students couldn't tell that he asked a question until he stops and stares and that's how we figured out. He doesn't even know whats on the exam. Do textbook questions since lectures are pointless. Labs are hard depending on the GA. Good luck.
