I did my exchange semester at UCLA and it was better than expected. The teachers were great and very didactic. We also received supplemental materials and those were also very complete. What I liked the most was actually the content of the classes, all so interesting like for example International finance, valuation and M&A. Of course, the Campus itself was also an amazing place to study and very welcoming, it is huge, and the infrastructure is very new and modern. Most of the classes had several working groups and that was a great way to get to know new people. It is fairly easy to find accommodation, there are several houses around campus, with different profiles, size and prices. There is also uptime support for most of them. Since the campus is in LA, there are a lot of activities you can do during the day or in the night, but the night life regarding clubbing is not the best because the clubs close too early (2am). For the new students I recommend that they travel as much as you can and try to meet new people always, to make it the best experience of their lives.
