A very polite request met by the most obstructive of responses from a couple of unhelpful show-offs.
I'm quite sure if they can pass what has to be a fundamental test of knowledge in each of the disciplines tested - and, of course, we only have their words for it - then I'm certain one as conscientious as you will pass with flying colours!
I wish I could help, however, I know no more than you about the content of these aptitude tests, my friend although if I was a betting man, I'd put money on this one coming up, afterall, it's the reason that aircraft fly in the first place:
Newton Three (Formally known as Newton's Third Law of Motion):
For every action, there is an equal and opposite reaction
Or more precisely:
If Body A exerts a force on Body B, then Body B exerts an equal BUT opposite force on Body A.
Just hope and trust I'm not teaching my granny to suck eggs, here!!
Good luck with your day at Oxford and here's hoping there's a good samaritan out there who will come to your aid.
