don't know how to get into a class or get coaches....

Hi Nokutenda,

The classes on Khan Academy are set up by teachers who already have classes and want to assign their students work on Khan Academy. They are not open to join; you have to have been sent a class code or invite link by your teacher.

This article shows how to add coaches to a child account.

If you want to add a teacher, go to the Khan Academy website and click Teachers from the bar on the right. Then add your teacher's email address.

I hope this helped!
