The first college that I went to just had the years of enrollment on it (for example mine said 2008-2010) I then switched schools to a local community college, and the ID on that does not have any year or anything on it. I have yet to have anyone question me.
You will be fine. I think, for the most part, there are shows that open their student rush for anyone, and others that have it just be for college students. So, that's why, I feel that I am never questioned.
