I would recommend take his class during summer cause i feel like he taught pretty good last summer but my friend who took it last quarter said he was bad.

This is a very hard class doesnt matter who you take its going to suck, but he is probably your best chance. If you're considering this over the summer take it! Its his last time teaching the course. He gives you all the material you need to succeed. Quizes and exams are just like the PS and past exams so rep those religiously and ur good

Ok, my last rating got removed so I'll try to be a bit more PG. This was the most unintuitively taught class I've ever taken. Quizzes were pulled from the hardest questions from previous exams. They tanked my grade so bad I was barely passing coming into the 50% final. Prof's retiring after this quarter so congrats to everybody taking 108b after me

Dr. Lew is a genuine sweetheart, charismatic and very intelligent guy. It's evident he cares about his students and wants them to succeed. However, this class operates on breakneck speed and will catch up to you if you fall behind. Watching the lectures and doing the practice midterms/finals over and over again helped the most. DO NOT miss section!

once you get what he means by “dont memorize” its much easier to do well. recognize the patterns and apply them to other contexts. remembering structures and names help but knowing general mechs/ explanations get you further. he makes sure you truly understand what is being taught. exam heavy. very caring humble and accesible outside of class.

Retook the class in the summer. You can see he likes teaching in a smaller classroom to make lectures more effective. Pace is quicker than the winter course, but easier to tackle as a M-R 11am. Earned a substantially better grade than the winter class. Quite literally, just do the problem sets and practice exams a kajillion times.
