Medicine Applications

Hi, I dunno whether or not I should be as worried as i am but I have not received no information from universities I have applied to for Medicine. They are:

Newcastle Durham Campus,
Hull/York which all the ppl i know that have applied have had an interview,
Aberdeen,
Dundee

Ive been predicted ABC in ICT, Chemistry and Biology (in that Order)

Ive heard info from my head teacher and referee that he received a call 3 fridays ago about me from hull/york and they asked about grades etc and I got a letter from them a week later.

Should I be worried, is anyone in this position?
