Lewis might actually be THE best professor I've had at UCSB. He's always accessible through email and shows a deep level of care and respect for his students. The material is hard, but Lewis really does his best to set you up for success. As long as you put in the work (textbook reading, book problems, lectures) you'll get at least a B

Grade based on weekly mastering chem problems, weekly quiz, 3 reflective essays(very easy), BACON quizzes and final. Most points came form quizzes and mastering chem so make sure you stay on top of material. Lewis was extremely organized and very caring. It's a tough subject but lewis makes it very bearable. Lectures are divided into 10-20min vids.

Lewis is an absolute gem. The material is hard, but you can ace the quizzes by watching the lectures, taking good notes, and doing all the book problems. It's honestly not that hard if you put the time in; book problems take a while, but they pay off. OChem wouldn't have the reputation it has if Lewis taught everyone's first course.

Lewis is a great lecturer who really cares about his students and truly wants what is best for them. The course itself and the topics are difficult but Lewis makes it understandable. He is very accommodating to any issues that arise. Do the book problems and do hw and you will be fine.

He is very organized, responsive, makes sure to answer all the questions, and usually responds to emails quickly, very kind, flexible when it comes to extending deadlines. Some lecture videos are not helpful, sometimes there are harder and more complicated concepts and lectures are not that helpful in understanding it. Some quizzes are very hard.

One of my favorite professors in the Chem department aside from Joseph. I really like his teaching style & really appreciate that theres no midterms/finals while distance learning. Very approachable with office hours basically 4 times a week which saved my grade. Practice problems can get you to pass any of his weekly quizzes too.

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.

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!

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
