Interesting, Pam, because in northwestern PA where I grew up, we often talked about high school freshman, high school sophomores, high school juniors, and high school seniors! I'd say that those terms were just just as often (if not slightly more) than saying "my son is in 11th grade this year.)
What to call a high school student is probably a regional thing. We tend to have more of those than we realize! Don't get me started on soda and subs vs pop and hoagies!
