Very solid professor. He lectures very slowly and mostly uses the chalkboard when lecturing. His exams are very fair. I would definitely take this class with Lewis again.

He made the material easy to understand. Very fair exams. As long as you do all of the practice problems you're solid. Reading the book is a must to do well. Good choice for 109A.

Awesome Professor. Teaches the subject incredibly clearly.

Professor Lewis is the most incredible professor. He goes slow and writes everything out on the board. You leave the class actually understanding Ochem. His tests are long and free response, so it's important to manage time. Beware the last question on one test was worth fifteen points and I was unable to get to it don't make the same mistake.

Professor Lewis is one of my favorite professors to date. He will write out elaborate explanations for any question you have, even over email, and usually extremely quickly. You can tell he really wants his students to do well, and I'm so lucky to have taken one of his first taught courses here at UCSB. He comes across as very humble and caring.
