so my DS, 3rd year maths student, sent me a one line message last night saying he plans to give applying for a postgrad course at Oxbridge a shot.
This was a bit of surprise, and it is not for advice/information for him that I ask, but I would just like any background information that any knowledgeable mumsnetters know on this subject. I know absolutely nothing about this route of study - I didn't go to university and I just want to be able to nod in the right places, ifykwim :) otherwise I will have to resort to Google :)
