Understanding why you are anxious might be more helpful. I had trouble with the same thing when I was a student. The things that caused my anxiety were 1) my unexpressed feelings and 2) my low self worth, and 3) shame. Sitting openly and "intimately" with the other students made me face myself and this was painful. Sitting in a big auditorium with all of the students facing the professor was much more comfortable.

What I did was express my feelings in therapy, even all the unexpressed ones from long ago. I also worked on my self worth by understanding how it got low while growing up and then in the present, when I would feel the low self worth, I would remind myself where it came from and that it wasn't right then (how I was treated) and that today I can feel good about myself. (I did this in the moment work every time that it came up and it did improve it each time). As for the shame I learned that we all have issues and it is okay to have issues and that I didn't need to feel shame for things that others also deal with and they do so without shame. It really is okay to have issues.
