I know a friend who has done this course recently.
Its a great improvement on the BSC.
4 weeks long.
Assessed work is 2500 word essay, chairmanship, leading a defence seminar, 15 min formal presentation, desk top brief to staish.
Other stuff is media skills, lots of input from the resident academics of Kings College London.
The emphasis is on free thought and debate and definitely not towing the party line.
As with courses your enjoyment will depend on your input, your fellow syndicate and your service and defence studies tutor (civvy academic).
There is an excellent library, food is ok, accom in same bldg is on suite. There is a scruffs bar and a honesty bar. You get your own laptop for the duration, and the college intranet and the internet (and pprune) is readily accesible.
You should have a good time.
Even the local curry hse is top notch.
Go do it. (My friend says.)
