Does any one know , how the classes were awarded ( 1st , 2nd upper,2nd lower..etc) for the direct entry students in UK universities , after completing their degree program

Assume that one international direct entry student has got a 1st clz degree after completing his final year in a UK university.And he has average score of 70 in his 6 final year subjects.

Also ,he got final year entrance because he has successfully completed Edexcel HND.

So the question is how the GPA was calculated for the fist two years..?..any one has an idea..??
