I'd recommend having a quick Google, as it can be dependent on where you are studying. For example, I've found a short blog about making the most of Freshers Week, which can then take you to a bunch of other related blogs about student life. I've also found this post, which is aimed at international students, but may also be interesting to read. University websites may also have posts about your social life as a student (e.g., University of Chester), which can also be quite informative.
I also find that depending on what I'm interested in doing, I can find loads of information on Google Maps or by having a quick walk around the city.
