You are kind to say so. I know some Oxford Dons and College heads socially, and can ask them about the process, and my nephew and then my daughter went through the Oxford admission process recently. I went through a different admission process many years ago, although you won't be surprised to hear that in some ways Oxford has not changed all that much since then. Oxford does change, as of course it must, but it tends to change slowly, and it is a great believer in "if it ain't broke, don't fix it" (although it would express that sentiment in elegant Ciceronian Latin).
I wish you every success, whether at Oxford or at another good university.
