I don't think people are trying to upset you, or get at you emznotts.
Having a first in a degree should mean the same no matter which university you go too. However the sad fact is, it doesn't. People judge you on what university you went to. It's what people do.. you can't change that.
I once read an article in the Guardian or Independant (I can't remember which now). However, it said that some employers nowadays would rather have someone from Oxford with a 2:2 than someone from an old Poly with a 1:1 in the same degree!!
It's extremely pooey, but it's the truth. The university of Leicester is i'm afraid seen as one of the 'better' universities.
