Tips on college life?????

So I’m moving into an off campus housing next week. I’m 27 so I’m a bit on the older side but I had to take 2 years off from college due to personal reasons. I’m going back to finish a math class and transferring to the 4 year school that is across the street from the off campus housing. I am going to be sharing a room which will be new to me. I just don’t want to not fit in and be awkward.
