Thanks for the replies!
I definitely have to just bite the bullet so to speak and make a decision! I would be aiming to study in 2011 so no need to rush things, lol.
I spend a good deal of my time teaching - from work experience to post grad learners and really enjoy it. Not sure how this would translate however.

LZ - I am a gun at radiation physics, the rest may be a steep learning curve for me also! I actually loved school (geek alert) - I was lucky to have some inspiring teachers and great experiences so perhaps I am putting too positive a spin on it? Good luck with your year ahead - bit of a juggle studying with a young child too!

Ginger - Can I ask for a bit of feedback re your cons - like marking/demanding parents etc. I would imagine that it all happens at once with marking/reports etc - how do you manage it? Also one of your pros was great hours - what hours are you at school and how much out of hours work do you do? Initially? Ongoing?

Thanks again!
