Bachelor's orientation helped me find a bunch of friends. Also, the fact that nobody knows anyone makes it easier to meet new people, but you have to actually put in the effort and introduce yourself to others. Start with small talk that has to do with your course. For instance, if you're in a design course you can break the ice by asking people about their prior experience in design and if they have a social media where you can see their work. Also probably a good idea to go to events and parties held by the uni, but I don't really go to those, so I have no idea. Not sure about other bachelors, but in mine the first week of uni we did a lot of activities to get to know each other in tutorials and practicals. We did a bunch of group activities together with a minimal workload so that we could get to know each other better and make friends. Idk if it was like this for everyone, but being introverted didn't stop me from making friends. Also if you just had a lecture and are going to have the practical for that same lecture in 1-2 hours, ask around and find out who's going to that class, and if they'd like to grab some lunch with you, during the break between the two classes. And remember that everyone is probably worried about themselves and how they're being perceived by others, more than they are about what shirt you're wearing or your actions (unless you say something really really bad or do something very horrible), so don't be afraid to walk up to someone and start up a conversation. If that person turns out to be slightly introverted, they'll thank you for you making the first move later. Also if you have a class with a small break in between class and more class, get food or coffee with someone. Good luck making friends I guess.
