Don't mind too much. Every stratum may appear. The most important thing is to get on well with your current roommates. In fact, not being in the same class may be more conducive to communication and more informative. Also, even if you want to get along well with your classmates, interpersonal relationships in college are very important. Greet warmly when you meet, and those sitting next to you can chat in class. Many things depend on the election, don't go it alone. I hope it helps you!
