109A . Lewis R B 4 Years Ago

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.

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.

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

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

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.

Cool guy, tests are always hard but that's OCHEM. Really fun to talk to during office hours

Dr. Lewis was a great organic chemistry lecturer -- he walked through reaction mechanisms on the chalkboard in addition to displaying useful notes in his PowerPoint slides, and asked occasional iClicker questions to drum up student participation and gauge where the class was at. His exams were fair, but are subject to change as Dr. Lewis is new.

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

I'm not a big organic chemistry fan, but Rob really makes it a blissful experience. It's very hard material, but if you go to lectures (and enjoy his occasional memes and funfacts), read the textbook, and do book problems, you'll at least get a B. Which is pretty much amazing for a student like me. 5/7 recommend. He's amazing.

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.
