dont want to kick up a fuss but exactly how much is it going to be and when is some one going to take money out of my acount for it. (poor student have to count my pennys)

You should have been charged Dom.

Last Wednesday (29th March) you would have been charged.

I think it's £130 for the trackday + race entry

or

£80 for just the race.

I also understand that there will be a further charge for insurance??? but I'm not 100% on that. When I spoke to the ACU on Monday, that's the impression they gave me.
