If you are referring to the Nav DLP, then the first test is on sections 2-7 and 10. Well, that's what us July intake had a few weeks back.
The other sections are "re taught" in the first few weeks. No major drama. It is multiple choice, except for a few variation/deviation and track/heading questions where you just work it out yourself.
I'm not in a B&B, I'm house sharing, but Westby Road is apparently the place to be for B&Bs. Some people have differing views on what is good and what isn't, but on the whole the Strand, the Edwardian and Ravensbourne seem to be most popular. The Au Levant (or the Boscombe Reef as it is now) is one to be avoided apparently, though some people seem to like it. If they like living with dirty kitchens, etc that is....
