By far, best MCDB professor I've had. Really hammered home on what was important, and 4 months removed still remember a lot. Great job of using concepts to drive memorization and making the subject matter unforgettable. Very accessible in office hours, and it is not a class where bs gets in the way of doing well. Highly recommend

Great professor! Really teaches the conceptual aspects of the class well, I still remember all of it weeks removed. Super kind and helpful in office hours. Hard class, partially due to large amount of material requried on own time but truthfully material in the class should be taught over 17 weeks not 10. Overall great prof and fun class.

Similar to others! Professor Lew is a great guy. That being said, his lectures are pretty disorganized. It was kinda hard to gage the big picture until I went through the practice finals. But, I feel like I learned the most from this class than any other class. The final is hard, but nothing crazy. Practice finals and midterms are your friend.

Mixed feelings... He's a really nice, approachable guy & lectures extremely well. He struggles to be succinct though, & piles on tons of work for you to do outside of class. I disliked watching all his prerecorded lectures on our own time. Shoutout to my amazing TA for getting me through this course!

It is v difficult to gage what Lew wants you to have memorized vs what he wants you to "understand". His finals are notoriously difficult, there is an excessive amount of work given that you must watch a video lecture before every lecture, on top of weekly quizzes, problem sets, and additional homework. He often gets lost in his own analogies.

Pretty entertaining so it's hard to fall asleep in class. Admired by many students. I would take more of his classes just because he's one of the better bio/chem teachers at ucsb. The Midterm was fair. If you participate more than once he'll call you by name. Overall a super caring and down-to-earth professor that knows what he's talking about.
