Went to the FLYER show afew months ago and did the GAPAN tests last month at Cranwell.
I am only really interested in ab-initio training and all the main schools are at the flyer show. It's very usefull as you get to meet people currently ont he courses, I spent about 20 mins having a 1-to-1 with FTE, OXFORD, CTC and Cabair. I also spoke to GAPAN and they advised me to do their Cranwell aptitude tests.
The test GAPAN have on the day is a 'taster' of an aptitude test and I would really advise you do the real ones; for both the result and the contacts you pick up.
