what to expect for advanced entry?

Hi everyone. I applied for advanced entry into 2nd year of a course and got accepted. I had done a PLC course equivalent to 1st year a few years back which allowed me to skip.

I'm wondering if anyone else has done this and what should I expect? I'm a bit nervous now imagining people already having their friend groups/knowing what to expect and me being utterly clueless and not knowing anybody.

It's a small college and i'll be missing the first few days due to a family holiday which doesnt help. Any advice would be appreciated, thank you!
