109C . Lewis R B 1 Year, 15 Days Ago

had him for the whole 109 series, is a great lecturer and provides very useful practice exams before the exams. doing the practice book problems is necessary to succeed on exams. very kind and understanding when you dont complete hw on time and office hours are helpful to clear up confusion. difficult course but put in the time and you're good

109C . Lewis R B 1 Year, 1 Month Ago

Had lewis for 109 B/C, & he is one of the best professors I've had at UCSB. I don't understand how he manages to make such a complicated subject so well organized & so much easier to understand. He has the sweetest energy and is so kind. He wore Hawaiian shirts every Friday. He does his best to make Ochem as bearable as possible, & has fair exams.

109C . Lewis R B 2 Years Ago

Robert Lewis is seriously one of the best professors here and he really cares about his students. The bad reviews from his class are from those who either got a bad grade or simply didn't put enough time. Organic chemistry is hard in itself, but Lewis' exams/quizzes were always fair. Nothing was unexpected on the exams and do book problems!

Goat, highly recommend for ochem. He was very accommodating during the pandemic and even tho ochem was easier online than in-person, if you do book problems and keep up with the readings you'll do good in the class. His lectures are helpful and held discussions sessions where he'd go over material that was in the weekly quizzes. Really nice guy!

One of the best professors I've ever had. He readily admits mistakes and regrades quizzes/awards points when he messes up, and answers every email quickly. He even made time to go over a quiz with me over zoom fall quarter. Genuinely cares about his students, and even though the class is hard, he makes it bearable. If you can take his class, DO IT!

Professor Lewis is by far one of the best teachers I have taken at UCSB. I took him for all of the ochem series. These classes are definitely some of the hardest classes you'll in your second year at school but Lewis manages to simplify and tackle the course extremely well with thorough and neat lectures. Read the book and always ask questions :)
