DS should be going on an international year between Y2 and final year of his degree. I know that the tuition fees will paid to his UK university and will be the same as he would pay for a year in the UK. However, I've no idea of other costs.
He hopes to go to a state university in the US (fall back position is a German university). Any idea about living and other costs? I have a feeling that Bank of Mum and Dad may be called on even more than usual.
