On my Post-16 PGCE we are in university 2 days a week 9-4 and we are at our placement college 3 days a week. Times vary according to which placement you are at. We had an alternative placement for 2 weeks midway through the year. I went to a secondary school for mine, but other students went to prisons, community centres and football stadiums that have education programs. We get all of the school holidays off, but there is a lot of work to do so these are mostly spent doing assignments. Teaching is not an easy profession and the workload is intense. You will be working late and you will be stressed, but people do it and you can too.
