I guess that the difficulty from Aberdeen is the 2 hour drive to Inverness or the 1.5 hours to Dundee or Perth? However, there could be an opportunity for these schools to undercut FAS in Aberdeen and take any students down south or North-West!! For reasons mentined earlier this might actually be a better option due to weather and commercial pressures.
Bit of competition might also bring down the prices for all concerned! Have FAS indicated the prices that they are going to charge in Aberdeen yet?
