Fall 2018 - Where do I begin? Tobolowsky is probably the best professor I have had at UCLA. The class itself (Chem 14D) requires a lot of time and is pretty hard compared to the rest of the chem classes, but Tobolowsky goes to the furthest extent to make sure that his students are well prepared for the exams. He offers extra help on Sunday evenings by live streaming a weekly recap on Youtube. His office hours are really helpful, his slides are very clear and organized, and he is really funny. I would take this class over 100x again. It is hard and does require a lot of time and effort, so be prepared to work.
