extracurricular activities

I looked at the commonapp and there are 5 boxes/frames available to tick, to mark,grade level, post-graduate. What does it mean?

Refers to the grades/years in which you took part in those activities

Well, don’t we send only the grades/marks received in the 4 years on high school? Why it isn’t the same with EC?

For each EC, you mark the boxes that apply. Maybe you played field hockey in 9th grade, but never again; you would only check the ‘9’ box.

Okay, why isnt there 8th grade to check

Well it’s the same reason there are five boxes rather than 15. The form’s compilers put on what was asked for by the colleges. Do you have an alternative theory?
