I'm doing the brush up course there in May. I have booked a B&B which is £125/week and then £6.50 a night for dinner. I guess then you need to add in Lunch, although my B&B think they said they could provide a pack lunch as well.
As for exams, Think the nearest travel lodge is about £67 a night! I am planning on Commuting as can't really justify the expense especially when I only live 45 minutes from Gatwick
Hope this helps
