If you can take 1B with him DO IT. He technically takes participation via online questions but honestly, I would just wake up, do them, and go straight back to sleep because its based on participation not correction. The homeworks are decently challenging but I do think they prepare you really well for the midterms and final. Still, they do not take more than ~3-4 hours a week. I would go to lecture the first few weeks before I got lazy and honestly hes a good lecture and a decently funny guy. Hes passionate, an engaging lecturer, and a good professor all the way. The best part about his class though is the simple fact that his exams are EASY compared to OTHER 1B professors. 1B as a class is going to be hard regardless but compared to what midterms/finals other 1B profs had his class is just way way way easier. Also, you can just read the lecture notes alongside the textbook to get a good understanding of the material. Hell, you can literally JUST read the textbook and probably get an A in the class. I literally just didn't feel like studying for the final and didnt learn the last ~3 weeks of material, bombed the final and still ended with an A- in the class. Would recommend.
