Hosea is an awesome guy. He's super nice, and very engaging. The class is instructed like his graduate course (244), but covers less material so it is very rigorous. Though it was tough, especially for someone who had an awful organic professor at community college, if you put in the effort you can manage the grade you want. Homework was challenging but only graded for completion and going to review sessions was incredibly helpful as he would give us some of the questions before hand to discuss them with our peers. His teaching style is different than most but that's what makes him so amazing. Definitely recommend taking him if you like organic chemistry.
