Fall 2019 - Zocchi's 105A is like what you would expect for a university physics class. His lectures are clear and he's really a nice guy. The key of this class is the formulation of Lagrangian, and that's something you have to do a lot of practice on. Homework problems are hard and really needs some time, but they are really helpful for me to know the course materials. Sometimes there are some problems that requires a bunch of calculation, but they will not appear on the tests. Tests are somewhat difficult. They mainly focus on the ideas and concepts, so once you've figured out what you should do, the calculation would not torture you. And tests are curved so seems like we will be alright.
