I completed my PGCE a few years ago and I won't lie it is tough!
Depending on your uni requirements you should be teaching your full student teacher timetable by November...11 hours a week for me.
Be prepared to spend a LONG time planning at the start but it does get easier.
This is an opportunity to have fun with some ideas you might have and if they don't work as well as you'd hoped just reflect back on why (was it your delivery/prep/not suitable for the kids) and build on it next time.
SHARE SHARE SHARE resources!! Between your cohort, and placement schools....and any other student teacher you can find. Take what they have (if you can) and put your own twist on it. It's good practise for the future and there is no point trying to reinvent the wheel each lesson!
It goes ridiculously quickly and before you know it you're in a school teaching 20-22 hours a week!
Not every lesson will go well but the important thing is to reflect back on what could've been done better and build on it, you're learning to be a teacher so no one is expecting you to be perfect from the get go.
Some people can be crap at giving feedback to you, but it really is such a useful tool! Ask other teachers how they think the lessons went, what could you have done better....you can even ask the kids how they liked the last lesson (well...some classes you can!), what would they like to see more of, what they didn't feel worked for them. The worst PGCE students I came across (during my training and since) were those that just simply refused to accept feedback (and yes sometimes criticism).
Sorry, this turned into a huge essay!!
Best of luck for the coming year!!
