Professor Zocchi is one of the worst teachers I have had. I'm sure he loves physics, but he is not effective in teaching the material: lack of articulation and very diffuse organization. I cannot say there was more than 1 or 2 days in which I actually got something out of his lectures. Upon looking back at my notes, it's hard to make any sense because all he does is write equations without sufficient explaination.
One upside is that his tests are pretty straightforward and people do pretty well.
