Yea, I mostly remember trauma bonding with classmates at 3am working on a project due at 8am

Electrical engineering major here, and it was very much the same. Very helpful supportive

There were a few hyper competitive people who were always trying to finish everything first to flex on everyone, they hated me because I finished projects earlier (I helped people that were having issues when I finished, they caught on and I got some snotty messages about being a try hard... I just had a lot of free time at work and the projects were easy to me). Along with a few of these in each class, I had some people that were just moochers that actually sucked and just copied other people and constantly did leetcode challenges or whatever, I ended up with 2 of them in my senior project and they did almost nothing even when asked.

That said, a very very large amount of the people I met were awesome supportive people, both in my comp sci classes and upper div math classes for my minor. We were remote for all but 1 semester of my degree and I lived an hour away from the university so I didn't end up making any lasting friends, but at least once a week I had study/help/hangout sessions with people I met in group projects, people they met, etc. A few people would show up to copy code and answers, but nearly everyone was great, and would pitch in to help others in the group if needed. There will always be snotty, lazy, and competitive people in every field, but they are (almost) always the extreme monority
