Don't let them tutee's (kids you be tutoring) ask you something you don't know.- and if htey do... show them how to look up the answer... better yet have them do the looking up as you guide them to finding the correct answer
If you are tutoring its because someone needs your help. Keep this in mind when u feel frustrated cause they will be frustrated too
Are you the tutor or the tutee?
Then practice patience. :-)
