Paolo is great! He is an awesome and caring professor. He explains the concepts well and his notes are clear. Not too many homework assignments, some problems are easier than others. Midterm and Final are a lot like the practice exams he posts. No surprises, great prof.
Paolo seems like he cares about us. Unlike most professors, he's very good at answering the question the student asks rather than some tangentially related question. Tests are very similar to previous tests, so the practice tests he gives you are very important. Homework is difficult, but not as particularly so for a junior class.
Paolo is a glorious man. His grace and sincerity are sometimes overwhelming, but he conveys the material very clearly, deriving equations carefully and methodically. If you ask a question, he'll answer the crap out of it. One of the most genuinely concerned and helpful professors I've had the pleasure of encountering.
