There is now a program that comes quite close to the original tests, I won't advertise it on this thread but if you go to Yahoo (it's not on Google yet) and search for PILAPT Prep you should see it.
A while back I bought something by CockpitWeb? which was a bit pants to be honest and costs twice as much.
I recently failed Stage 2, drat! but have been asked to re-apply in 6 months.
