average age of a high school sophomore
In high school a Sophomore would be 16 or 17, though they could easily be a year younger or older.In college a Sophomore would be 19 or 20, though they could easily be a year younger or older.f you â¦ mean what is the average age for a piano student to be grade 8, for example, I would say probably about in their early 20s (If they have been studying since in their teens, which is about average).
