Teaching others, even if you don't know the material too well, pays because your students will come up with bugs, problems, and questions stemming from misunderstandings that you can't even conceive of. So it forces you to go away and find out and explain more clearly next time around. Pretending to teach won't come close.
So long as you approach it honestly; "you know, that's a damn good question. I'm not sure so I'll have to come back to you tomorrow." Then make sure you do come back to them. Or walk through the language reference with them. It will move you massively ahead in knowledge and soon kill off any misconceptions. It's OK to admit you got something wrong earlier in the week. Just don't do it daily. :)
