United Kingdom grading system?

<p>I'm having problems finding a site that will directly tell me what the grading system is in the United Kingdom.
What number percentage qualifies as an A,, B,, C,, D,, and F.?
I'm hoping to get into either the University of Cambridge (A hefty hope- I know. :/) or the University of Manchester.
And what exactly is A*AA,, or AAA.? </p>

<p>Can someone please tell me the UK scoring system.?</p>

<p>I think you should post this in the International Students forum. Lots of Brits over there.</p>
