Comment from student: Hello, mam respectfully don't bother to answer my question if you don't understand
or if you don't know the answer let another tutor answer.

My response:

When the tutor answers to the student, the student must stay in attention.

The only words he can say in response are "Yes, sir", or "Yes, maam", or "Thank you".
