2. It's hard. In Italy, it is really impossible not to speak Italian. If you rely on English, then you can read a small part of things, but you can't say it, you can only make gestures.
3. Turin University of Technology will provide full scholarships for outstanding students, with an annual amount of 10000 euros, while some scholarships, mainly EDISU scholarships, will be provided to outstanding students from low-income families, with an annual amount of about 4,200 euros (due to the economic crisis this year and other reasons, most students have been unable to get this money, accounting for about 67%). EDISU Scholarship, also known as Piedmont University Student Welfare Scholarship, is mainly for undergraduates, postgraduates and doctoral students whose annual family income is below 1 0,000 euros. When applying for an EDISU scholarship, you can enjoy free tuition and apply for a scholarship of 4,200 euros/year. The evaluation standard is that freshmen are only evaluated according to their family income. From the second year, in addition to family income, applicants are also required to complete the credits stipulated by the school.
The specific figures are unclear and need to be answered by professionals.
5. I haven't been to school and I don't know. However, as a top university in Italy, Turin University of Technology, I think the campus environment, cultural atmosphere and students' quality will not be low.
