There is no written exam, which in way was a disappointment; I think I would like to have had a follow-up test after, say, a month. But as they are, these courses are expensive to provide and to attend, so I should perhaps not wish for things that would add to cost.
We were issued a booklet Paediatric First Aid Made Easy, about the size and length of the Highway Code, and equivalent in level of difficulty (roughly) to a core GCSE revision guide. This will be my reference for the next three years (after which I shall have to take a refresher course); I hope it will be only for reference, and not be needed as an instant handbook.
