Sim/London Met
London Met is highly recommended. I had a great time there (LGU in 2002) and think that the ground school staff were superb. Overall most of the class did very well. Notes have been re written and apparently are now much better.
Re the sim, there are two. I cant speak for the more sophisticated one, but the older one, apart from being a little old and long in the tooth (and noisy) is great for the scan. It is possible to hire at an hourly rate (I think) of £25, with a small concession for ex students. At this stage there appears to be a change over of the staff with regards to the sim.
Hope that this assists and I wish you the very best!
