Oxbridge applications (again)

As with every year, we get a bunch of questions about applying to those two schools. Here's the quick rundown:

Both schools require interviews. Cambridge will fly a couple of admissions tutors to Singapore and they will interview you (except for medicine - you have to fly there). Oxford has been doing Skype interviews of late.

So, deadlines:

Cambridge – 20 September if you want to be interviewed in Singapore. If you don't mind flying to Hong Kong or the UK, your deadline is 15 October.
Oxford – 15 October

Your UCAS application must be submitted by those dates as well. A little known fact is that you can add schools to your UCAS app even after submitting it. So you don't have to have finalized all your choices to apply to Oxbridge. Just make sure you write a decent essay, and later, once you've decided how to allocate your remaining 3-4 options, you can add them and your application will be sent to them (until UCAS's system-wide deadline somewhere in early January).

Also, do keep in mind that you can only apply to either Oxford or Cambridge, not both.
