Sussex and Surrey will accept you, but the other ones have a minimum entry score of 7 and even 9 for some of them like Warwick...because of their reputation..not to mention about the fees...still Surrey for example has very good job prospects .... 80% of the 12,000-strong student population study on courses that include a work-based professional training year. The university is famous for its consistently outstanding employment record. The student union has some of the best facilities in the country, and a packed calendar of events and activities.
I have applied to some for a Masters at some Uni's in UK as well and I would go to Surrey for several reasons...

let me know if u have more questions..
Iuliana
