I personally think the PGCE workload is quite hyped up. I have just finished term 1 of primary PGCE and am a bit bored of people on my course complaining about the workload. I think the problem is that most of them have come straight from under grad courses and yes, it's a bit step up from that, but as someone else said, welcome to the real world. Compared to my old job this is not that bad. I used to work 10 hours a day 5 days a week including Sundays, and it was quite stressful. I'm really not finding PGCE so bad.
That said, I'm not having to do as much as some people on this thread - my uni was assessed last year by ofsted and were told we had too much work, so they've massively cut it down this year. This pastoral care is excellent and they're really focused on the work making us better teachers - not just essays for the sake of essays, which it sounds like some people get.
