<p>The link to the Oxford admissions pages that Insane Membrane posted will give most of the detail you need to approach the application process. Remember you must decide and indicate what course you want to study. I think you said on another thread, NJPitcher, that you were interested in PPE. From the general admissions pages (top left on the link) you can get to the course specifics. E.g. for PPE there is an extra written test set by the University. </p>
<p>The interviews are important and are intended to be another test of your interest in your chosen subject as well as your ability to think around it. </p>
<p>You have to send an application to Oxford and another one to UCAS (University & Colleges Admissions Service). The UCAS system allows you to apply for up to six UK universities at one go, but there's nothing to stop you just putting down Oxford. </p>
<p>You need to be making your mind up whether to apply very quickly as applications must be in by 1 October. If you are called for an interview they take place in early December (North Americans can be interviewed in New York or Vancouver). You would then be told around Christmas if you have been offered a place. In most cases an offer will be 'conditional' on meeting specified conditions. In the UK these will usually be to get certain grades in A-level exams in the summer. For the USA it may well be specified grades in APs.</p>
