Some students are worried about the fact that classes are taught in English, and that this may be an obstacle to the understanding.
Professors try to use a basic English and a simple accent, they are always available for clarifications in Italian and often give pointers to additional material to help students. Furthermore, many classes are recorded, and made available on each student's personal web-page.
To let you check if your knowledge of English is good enough to understand classes, you can find below a video of the first lecture of the chemistry course, held by Prof. Guido SARACCO. The system used to record this video is the same used to record all classes.
