HI, Also a PGCE student this september so getting my supplies bit by bit. I got my Pirong diary about a week ago. I got a nice 'teacher's planner' A4 and it certainly looks good but I think there is a lot of wasted space. I also got an A4 day-to-view diary which is really useful. And a wall planner which is totally rubbish (so avoid getting them from Pirong!) Overall, they seem pretty good but I do think they'll be pretty bulky but I like my A4 over the A5.
