There are no major cliques I've noticed. It's obvious if your a nurse you will hang out with fellow nurses at school but I've enjoyed seeing students still stay friends with other students they had one class with a few semesters back. I myself still smile and wave to fellow students and professors I've interacted with a few semesters back. It's a peaceful school where every seems to get along.
Since I am currently attending a community college, there are a lot of different types of people, of different races/ethnicities, who speak many languages, and come from very diverse backgrounds. I think that among some students, there is a feeling of ethnocentricity, and therefore have a tendency to look down on others who are different from them. I think that this is very sad, because, having been on the other side of such discrimination more times than I'd care to say, I understand what a toll it can take on a person. I wish that people would recognize the potential outcome of their actions, and think twice before they did them, so as to avoid hurting someone else. However, I will say that, as a general rule, there is quite a bit of interaction and socialization within, if not between, people involved in clubs/groups. I do not feel as though the "discrimination" is bad, or even severe enough to be classified as such, but it is a trend that I have noticed.
Also, again since I am attending a community college and predominately taking evening classes, a majority of the students are adults with established careers (they may work during the day and take classes at night). These people are typically more dedicated and committed to their academic life than are students who are, say, fresh out off high school.
Overall, I do think that I see a lot more diversity and people from all walks of life at my college than one might see at a university. It has taught me to accept people for who they are, and made me realize that most of them are there for the same reason as I: to get an education for future career advancement.
I am a mother with two children. All the professors are willing to help in anyway and want to see their students suceed. You can always find a student to study with and the study area and the students are happy and willing to help each other out.
