109A . Lewis R B 2 Months Ago

he was so hard and honestly did not prepare you well the only reason people did okay was because of the curve.

Lewis is a good lecturer but this course was made for giving up your major. I will hate ochem for my whole life

CHEM109ABC . Lewis R B 2 Months Ago

Though the content is hard, Lewis does an excellent job of explaining it. You can tell he wants all of his students to be successful! He is extremely easy to reach outside of class, an excellent lecturer, and an overall nice guy. My advice for studying: form lecture groups, do book problems, and attend lectures.

Live laugh love Lewis. His lectures are so clear and follow the textbook almost exactly. He makes himself so accessible, use the discussion forum!! Obviously a hard class but he provides so many resources so success is possible.

CHEM109ABC . Lewis R B 5 Months Ago

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 :)

Dr. Lewis is a great lecturer, especially given the difficulty of the material he teaches. His tests, grading, and curves are very fair. As long as you go to lecture, study, and do assignments, you will do well. I would recommend reading the book chapter of any confusing material to gain clarity. I would also highly recommend the book problems.
