Hi Zabikhano308,
I am sorry but Khan Academy can't provide you with a tutor or coach as we can't screen individuals but a coach can be someone you know in Real Life like aunt/ uncle , parents, extended family member or perhaps ask your classroom teacher if they know of anyone who is in your School who may be willing to be a Coach. Next we have a Study group forum in Zendesk peers can answer questions you have about math etc. and while studying under Khan Academy math and other subjects etc. there is a box for questions you may have about a subject again peers and sometimes teachers, guardians respond to the questions you may have.
