They are apparently looking at various options being studied, all of which would increase the number of venues and the number of sittings available while reducing the waiting times (possibly to minutes).
The costs were not mentioned, but may increase due to the expense involved as I am sure students will bear these, but as tropo pointed out this may be set against cost savings of travel and accomodation. It is good to see these issues being raised, and I hope hte CAA will get word. I certainly will mention it next time I see one of the fine people from the Belgrano!
I agree (of course!) that there should be a centre down here, Keith. In fact there was one, at least when I sat them in 2000, but even then it had not been available in living memory.
