Lewis's class may be difficult, but he is one of the best professors out there. He is organized, very accessible out of class, and cares for his students a lot. His exams are overall difficult but as long as you read the textbook and do mastering chemistry and book problems along with the topics he covers on his lectures, you're guaranteed to pass.
Amazing lecturer! Lectures were organised and clearly structured to make you really understand the material being taught. Lewis is a really friendly guy and helps all students. To succeed it is important to read the book before lecture, attend the lecture and do practice problems. Not too difficult if you also put in the recommended work!
One of the best profs I've ever had; his lectures are clear and helpful, his tests are straightforward, and he's always willing to help after class. I had Bruice the first time and got a D; with Lewis, I got an A. He always answers emails quickly and lets you do test corrections (and he gives so many points back!) Take his class and thank me later!
Dr. Lewis is a real gem of a Professor. He genuinely cares about teaching and your success. This class by nature is really hard but Lewis actually made it fun. Track down his old exams, go to CLAS, do book problems, etc. I have emailed Lewis tons of questions and he answered quickly and even made me my own worksheets to help explain and teach!
Professor Lewis is one of the best Professors I've ever had, he is a great lecturer and really cares. His tests are kinda long but fair. Also he offers extra credit and plenty of opportunities to boost you grade (i>clicker, HW)
He's a wonderful lecturer. He uses the chalkboard so you can't rely on slides online, but this means the pace is perfect in-class. Answers questions clearly. Keeps you engaged. Tests had some tricky questions but nothing unreasonable--understand the MasteringChem and do book problems. Super helpful in office hours. 5% easy extra credit.
Skip through materials very often. Tons of questions every exam.
Clear and intense lectures. Read textbooks before the lecture or it would be hard to follow. He spends much time on mechanism which might be good for understanding the materials of organic chemistry
Lewis has hard exams with low averages, but if you want to study hard, he is the best person you can met in UCSB. Always respond to email quickly and patiently. He is a great lecturer and teacher, hard exams is by no means a reason for not choosing his course
He is the best ochem professor ever. His teaching is really clear and straightforward. Go to the lecture and take notes, you will understand the knowledge. He really cares about students and he's really helpful (he replies emails quickly). Exams are difficult for sure, but if you get more than 75% in every exam, you can get an A.
Professor Lewis is the best ochem lecturer I have had at UCSB. His tests are difficult but 100% do-able if you read the book, attend lectures, and do ALL the book problems. The curve for his class is also super generous which is amazing. Utilize his office hours - he's so helpful and makes difficult concepts much more straightforward.
The course itself demands a lot of work, do the suggested problems and textbook readings. Clear lectures, participation is mandatory. and counts toward your grade. Has extra credit opportunities that help with a small boost. Tests are VERY fair to material covered in class, and he allows regrade requests with a written explanation.
Really solid lecturer and helpful during his office hours. Lewis was clear on what his exams were covered and imo they were all fair. Make sure you go to lecture, read the book, and do the txtbook problems. He also offers extra credit
Lewis is an amazing professor. He really cares about his students, his exams are fair as long as you do the book problems. Overall, this class was amazing! Definitely would take lewis again!
Prof Lewis is crazy, crazy good. Super helpful during office hours, and always tries to give students the maximum number of points possible. He has extra credit points, and re-grades tests himself. His tests are representative of book problems and Mastering Chemistry, which makes the homework less tedious. His lectures are slow and easy to follow.
You know they good when they get a 4.7 rating teaching only ochem. His handwriting is neat af and the explanations are great in lecture. Office hours also super helpful. Only thing is he needs to get active on reddit again :P
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.
Professor Lewis wasn't horrible but wasn't the best either. He likes to gatekeep his material, doesn't post ANY notes from lecture or any exams taken during the course (only answers). He is very laid back. But I will say that his exams are easier and are very similar to his worksheets. Overall I think he is an okay ochem professor.
Ochem is hard in general, but Lewis does his best. HIs exams for 109C were not bad, but they were filled with questions that tested specific textbook knowledge, so READ THE TEXTBOOK. He's super responsive/helpful in Canvas discussions, so take advantage of that too. 109C wasn't as bad as 109B, but you still need to work a lot to get a decent grade.
OCHEM is definitely tough and requires self-discipline and commitment—you'll feel overwhelmed at times. But Dr. Lewis is one of the best professors out there. He teaches with such clarity and calmness that the material feels more approachable. He's also kind, patient, and genuinely encourages questions.
