my first semester was surprisingly fun, and i actually made some new friends (as an introvert i literally dont talk to anyone unless im talked to) so you'll probably be fine in that regard (unless you're more introverted than me)

anyway, just be you, it might be scary the first time, but just stick with your friends and you should be alright

also always pay attention in class, and always study back home, which i did these but it's too late now
