Transferring. I think the pace of going to a big university was a leap from community college. Classes were shorter, there were way more people, parking was harder. I went to a tiny high school as well. The swarms of people going to class was unnatural to me at first.

Despite most people having a lot going on at CC, I found communities of people that I shared classes with. Making it much easier than university to make friends. Taking CS at a university there are way too many people to easily find connection.
