1) If you were to apply to Balliol college, for example, and they rejected you, would you be deferred to other colleges or would your application to Oxford be rejected flat out?
2) Furthermore, if you submit an open application, are you first assigned a random college after which that college, and that college only, decides whether you will be accepted to Oxford or can can you application be selected from a pool of open applications by any college (i.e. not left up to the discretion of one college)?
