I'd already done my homework on looking for a distance learning groundschool, so the exhibition was very useful for talking to the final two, and choosing from there. As it turned out I found a realistic third in the shape of BCFT, and the chat I had with three of its staff was very helpful. I then got talking with the other two, Oxford Aviation Training and Bristol Groundschool, and both gave me very no-nonsense, upfront and open advice.
Having the CAA guys there was also very useful. I managed to get a key question answered on the spot, so the trip was made worthwhile by that alone.
Not much in the seminars for us rotorheads, though.
