Lewis is a great ochem professor. The material was clear and his canvas was very well organized. Ochem is a tough series and he definitely understand that. It's clear he genuinely wants everyone to do well.

Ochem is genuinely so hard that I would have changed my major if I didn't have Lewis just to avoid it. He is great at teaching and his videos are helpful if you have a hard time picking up concepts quickly in lecture like me. The other ochem professors don't have videos so keep that in mind. Ochem is hard no matter what, but he makes it better

Genuinely start doing textbook problems from birth at this point. You will want to drive off the pier after every exam. Study for this class every single day and make sure that you're actually learning why something reacts instead of memorizing how.

He's very helpful and is an awesome lecturer (especially for 109B). One of the best professors on campus tbh, reading textbook before coming to class helped even more

Very kind professor and wants you to succeed! Def need to spend as much time as possible reading the textbook and doing practice problems to pass. Tests are very challenging.

O chem can be difficult (even as a chem major), but Lewis is seriously amazing. He's extremely clear, tests are fair, and lectures very well. I love that he's so calm, and even if I'm swamped I'll still go to lecture because he doesn't stress me out. O chem is now my favorite subject. Amazing guy. 10/10
