In our country, Turkey, when someone wants to know if you're a freshman, or sophomore, or w/e (knowing if you're in high school, or in university) he/she usually says: (making a literal translation here)
Which grade/class are you (in)?
and you'd reply with
"Second grade/class." or "I'm a second grade/class student."
However, I've never seen this kind of reply, or rather question in English. How would you ask if you want to know the person's grade/class in university? And how the answer should be?
Besides that, my real intent for asking this is that I'm writing a paper (in English) and it concerns second-year students, but other people will also have access to that paper. That's why I want to indicate that it concerns only second-year students by adding a short text onto the cover page. I wanted to know what should I write to indicate that. I thought about
For second-year students
but I'm not even sure if these fit, or if there's something better to say.
I think the title and tags might need a modification as I'm not sure if they match with the question.
