Hi! You should definitely seek advice from people who have studied in Italy as international students, but in the meantime I can maybe give you some info as an Italian. Your biggest problem is going to be finding an English-taught programme, because unfortunately most humanities courses here are only offered in Italian. Plus, I might be wrong but I feel like degree programmes here tend to be a little more specific, so is there a subject or area of interest you are looking for?
Feel free to ask me any question!
