This is your study age. Please correct it?

Hi teachers,

  1. This is your study age. Please correct it?

Many thanks in advance.

More context is required.

This is your playing age. So "This is your studying/studies/study age?

Sorry, that still doesn’t make sense to me.

Okay, Madam BN.

  1. You are not of playing age. Correct?
  2. You are of studying age. Correct?

Yes - you are not old enough/young enough to play.
You are old enough to study.

Perhaps, then, you mean something like this:
This is the age at which you should be studying.
You should be studying at your age.

Thank you, Madam BN.
