I'm in the same situation! Apart from I want to swap my 3 conditionals for Sociology, for Magazine Journalism and Feature Writing. I sent off 2 late applications for this course but both got rejected,I feel because I rushed through everything. I'm going to do year 14 to get more qualifications and UCAS points, and I'm using that year to look round more unis and make more informed decisions so that this time next year, I have offers and everything sorted out as opposed to rushing and applying everything late.
However, if you really want to go this year, you have two (I think) options. Submit late applications (email the uni, they may say 'yes,just send us a new personal statement' or 'no.' :P Your second option is Extra.
