Medicine ucas application

Hi guys, I am trying not to freak out but I am
I have sent my medicine application to ucas and its being processed, I already received my login details for all my unis. However I realised i forgot to flag that im a UKWPMED student on my ucas extra activities section and its crucial for like 2 of my unis for a guaranteed interview and reduced offer... i dont know what to do and the deadline is in 2 days?!?!? pls help

I would suggest that you ring ucas tomorrow and ask them for advice.
