Really the best advise I can give is to make sure what your teaching
is true. And if the student doesn't get it right away take the time to
go back and teach it to them again. I know sometimes it gets frustrating
but just take your time. You have all the time in the world.
If they ask a question that you don't know the answer to then look it up
that way you'll learn the answer and so will they. I've had to do
this several times.
Right now for me it feels like I'm a teacher. Even though I'm only
13 it feels like I have about 3 students already. lol I'm happy to help them
though.
