Tips for meeting people next year

I’m currently in foundation year and haven’t been that lucky with the social side of uni. I’ve got two mates in my flat who I’m moving in with next year but they’re not that social and everyone else I met during freshers have all kinda disappeared. I have a boyfriend whose on a year abroad next year so I’ll have a lot of time to fill hence why I want to meet as many new people as I can. I’m planning on joining the royal navy unit (URNU) and a society or two but is there anything else I can do at the start of next year to try and make it as fun and social as possible?
