How to deal with unfriendly clmates?

If I was you I would get to cl early, and look at the people who seem friendly or won't treat you like you are inferior. They might be a little nervous so it comes off as being rude, but once you get to know them it will get better. I had the same problem, but I had no choice to work with my lab partners for chemistry. They never trusted me with anything, and really didn't let me participate in the labs. Unfortunately you are just going to have to deal with rude people your whole life, so you might as well start practicing right now.
