nav test - read the document a few times and get it to sink in and you'll have no bother
as regards b&b's - i stayed in the ravensbourne for my time (6 months) and i have no complaints at all to make, good rates, great landlord and good people (ATC only) staying in there. plus westby road is good for social/study depending on time of week

if you havent already, read through this whole thread. i agree it may take a while at 67 pages but there is heaps of info that has accumulated over time from loads of good sources and is pretty much all still relevant. if you have any specific questions then feel free to ask on here or pm, but i think you'll find the majority of your answers in detail are already on here
