Join a Facebook group if there are any for people in your halls and if you haven't already done so, then you can meet those outside of your flat!
You may also meet new people through your course next term when your modules change
I’m really struggling to meet people I click with a sussex as my subjects aren’t really me, I’m just rly looking for some mates to go raving if anyone knows any ideas on how to meet more people at Sussex I could click with please let me know
Look at joining sussex snow they are known for their partying antics. Im in the same situation the ppl on my neuroscience course aren't really on the same level as me, but long-term try reaching out to ppl at brighton uni maybe, brighton is less academic and a lot more FUN if that's what you are looking for, sussex students are very serious...
