Abby, if I were you I'd wrote a personal statement and see what happens - I would say to ring and see if you can still pay but they are pretty brutal - The payment deadline was only last night!!!!! didn't you get an email about it? I did, both through my booking with Vtac (a reminder to pay came on Tuesday) and through a subscription thing to something Vtac is in charge of.
Check Tuesday's emails and see if you didn't get a reminder - you might have good grounds if you didn't????
Anyway - read up on the website about supplementary offers and negotiated offers.....then read the uni websites about alternative entry pathways.
Or just take this as experience and relax with the babies for another year
