Pre Practicum

I'm going to start my first day of practicum in 4 days.  I wouldn't say I'm feeling nervous, but I guess there is a low level anxiety feeling about what will be expected of me.  I would say my associate teacher is very nice and easy going and I am sure it will all be fine - but I didn't really teach anything during the step days and I feel worried about that fact, when my other friends in Midtown seem to have taught lessons already.  I am also hoping I'll be capable of teaching a subject that I may not be very familiar with (like sound in science).  Fingers crossed!
