Right you are Luksy. Right you are.
Shuttle still exists as a brand but it's not widely used. Concorde, as you say, is gone. I am trying desperately to remember the questions on the initial test. You're given this on day two of your course and to be honest, it's not the biggest of deals if you fail (you won't - the pass mark is quite low).
If you have problems you can ask the trainers.
You'll find that a lot of the questions are largely common sense. Know things like the name of our CEO (Willie Walsh) and our Chairman (Martin Broughton). Know about the london airports we serve (don't be tempted to just say LHR/LGW as we now use LCY). A general understanding of the company will see you through a lot of the exam.
Check out
http://www.wikipedia.org and type a search for British Airways. Lots of seemingly pointless information in there that may actually come in handy on the day!!!!
Best of luck!
