Cold Soak,
Lots of info about the Sim assessment on here, the stuff that's been posted in 2007 is probably the 'best' bits to look at. Suffice to say, you're probably not going to be venturing far outside the UK.
The FMC - all you will be able to use the FMC for is remote tuning of VORs, ADFs, and ILS. (NAV RAD if you're a Boeing man)
LNAV, VNAV, FIX page etc not allowed.
Best of luck.
