There are many people in the university who are more scheming, but not only in the university, but at all stages, but the things and performances that TA people work hard at each stage are different. When I get to college, it is even more obvious and intense. When we grow up, the more complicated our social relations are, the more obvious our scheming will be. If you don't like ta, just ignore them, find some simple and like-minded classmates to get along with, make friends, and there are many kind people.
Personally, I think that the more people you know in college, the better for you to survive in society after graduation. Not long after graduation, I found that the conspirators in the school were nothing, and those who conspired in the school didn't have good interpersonal relationships in the end, which was quite annoying.
I hope you can exercise yourself well in college to avoid being caught off guard when you graduate, and I hope you can make good friends. Good luck!
