My DS is a fresher at Oxford and not enjoying it one bit - the intensive work load, the lack of contact hours, the general 'nerdiness' of it. He had wanted to go to York but, as he was predicted (and got) 4 x A star, we urged him to apply to Oxford (where we went - he had no intention of applying) and then, when he got his offer, to firm it. He very reluctantly agreed after talking to his teachers who said he'd be nuts to turn down Oxford, even though his heart was set on York.
He sees his friends from school having a blast at other universities whereas he has his nose to the grind at Oxford. He is now planning to see his Director of Studies and to see if York will take him from September (to read the same humanities course). He is not interested in my advice as DH and I 'got it wrong' and gave him 'duff advice' (his words).
I am not sure if I am up to replying to anyone kind enough to offer their thoughts because I feel so miserable/disappointed/guilty on his behalf.
