If you like, I have the preparation material for FTE in Jerez tucked away somewhere, I can't see it being hugely different. PM me if you want me to dig it out and mail it to you.
As for content the FTE process was pretty much as G-RICH said, I'd say it was pitched around GCSE standard, but I don't recall having any formula sheets to hand.
If OAA is what you want, don't count on getting through the selection purely because you have the money available. 8 people were on my selection at FTE, 2 were given a flat no, 4 were told to come back and re-sit certain sections, and 2 of us were given an offer there and then. This is by no means saying there isn't an element of 'show us the money and you're in' by the way, just that they do still turn some candidates away.
