What is the difference between hoc sinh and sinh vien?
Học sinh: School student (from grade 1 to 12).
Sinh viên: University or college student
Thank you very much
why is nhung thay va nhung hoc sinh not correct ?
Why is "những viên" incorrect?
because it doesn't mean what you intended it to mean.
upon hearing it, without any context, I might ask: "viên gì? viên đá, viên bị, viên bò?" (what kind of ball -- viên is the classifier for small round objects -- ? stones, marbles, meatballs?)
