I know this question has probabaly been asked a zillion times before, but just out of interest:
How many weeks' experience do you guys have so far? And how many are you hoping to get by the start of year 12 ( and by the time we eventually apply?)
I'm trying to convince myself to not aim for a specific number and just to do as much varied work as possible, just a tad worried that I'm not keeping up with it all though as a year 12 I bumped into today explained how he wished he'd done more earlier.
