I feel prepared to be in front of a classroom of adolescents. I feel at ease and comfortable around teenagers. I don't think I'll have issues with keeping their attention and respect.

What I worry about is content. How in the world will I fill 4, 5, 6 different classes a day? How do I put it all together? WHERE DO I START???? Is this whole thing supposed to be innate? Will my principal hold by hand and tell me what to do first?
