CHEM109A . Lewis R B 4 Years Ago

In a pandemic, you would think the professor would be more accommodating towards increasing the quality of teaching organic chemistry. Nope. You read the textbook and teach it to yourself and he gives a short 10 minute video over very complex topics. Only good thing is that about half of your grade comes from BACON, mastering chem, and essays.

The most caring genuine professor UCSB has to offer. He is considerate and understanding. He cares about his students and being a good professor to an extent I've never seen before. He is so hard working to ensure he thoroughly answers every question. Unlike most profs, he wants to actually connect and bond with his students. VERY approachable.

Lewis is a true gem. His tests can be pretty hard, but he's super straight forward in what he wants you to learn and what you can expect to be on the test. He also gives you the opportunity to get your test regraded if you missed points unfairly, and he gives extra credit. He's also funny and really made THICCPEPTIDE an answer to a quiz question

Genuinely one of the best professors I've had at UCSB. I don't like organic chemistry, but Lewis made the lectures interesting and broke the material down so that it was very understandable. The tests were very fair and followed lecture.

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!

CHEM109A . Lewis R B 5 Years Ago

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!

I LOVE HIM. Go to lecture, skim the textbook, do hw problems, attend CLAS aka put in the work and youll succeed. Hes so organized and lays out everything you need to do to succeed. There is some extra credit. Though he doesnt do a massive curve like Aue, the homework and clicker questions will bring your test scores up indefinitely. Very funny 2

Lewis is one of the best profs I've had, cares a lot about his students and always available to help by e-mail or office hours. Very approachable and kind. His tests can be tough but they're always fair. He doesn't try to trick you he just wants you to understand the material. Would 100% recommend him.

109B is challenging! Personally, I wouldn't take Lewis again. He is nice, extremely organized. He goes through each mechanisms so fast and expect you to have to do the application yourself. He doesn't explain, make relations between the mechanisms that help you understand. He is not engaging; his voice is monotone. Not the best lecturer. Nice guy

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)

CHEM109A . Lewis R B 5 Years Ago

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

Professor Lewis is one of the best lecturers I've had at UCSB thus far. He is really engaging and generally cares that students excel in such a difficult subject. Go to his office hours he is very straightforward and easy to talk to. Really changed my perspective of OCHEM and he uses a lot of memes while lecturing and real world applications.

CHEM109AB . Lewis R B 5 Years Ago

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.

He's the sweetest professor ever. He genuinely cares about his students. He's so fair and reasonable. Ochem is hard no matter who you take but at least a good professor makes it less depressing. You'll pass with a good grade with professor like as long as you put in the work. He's so precious wish I could take him for 109c also.

Best professor! I went from failing 109A with Bruice to A's with Lewis for 109A & 109B. He cares so much for his students, makes time for them, and is very easy to approach. His exams are tough, but he gives as much partial credit as he can. Attending CLAS, office hours, and actually reading the textbook and doing the problems will get you far.

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

CHEM109B . Lewis R B 5 Years Ago

Clearly cares about his students. Continuously assigns chapters to do at home that he can't get to in class. Teaching is straight out of the textbook and attendance is required so prepare to waste a lot of time in class. Book problems are somewhat helpful but there are discrepancies between the book and his tests
