Year 12s: what will be the first way you research your future options? >>

substitute one of my choices twice?

Hi, I think I've made a big mistake here and now I'm panicking..
I changed one of my options from Nottingham to Newcastle last night; but now I want to change it from Newcastle to Kings College London. After going to the track site though the substitute this choice button isn't there!

Is there any way to change a choice more than once? I've paid UCAS for my application I think its ridiculous that they make everything so mysterious and confusing. I would ring them but they're not open on the weekends and on Monday it will have been 7 days since I submitted my application because I submitted it on the 17th this Monday.

Is there any other way to contact UCAS or to solve this problem? Might I be able to ring them on Monday and get them to change a choice?

Thanks! I hope someone can help!
