If you’ve studied in Britain and want to enroll in a university from another European country, you will discover that grading systems can be very different. Some use letters, others use numbers or percentages, and scales vary from 1-5, 1-10, 0-20, and so on. Any university may use a conversion system of its own. The UK grading system is not very different from the Chinese, Indian, US or EU grading systems. The top grades go to individuals who succeed and get really high percentages and anyone who manages to reach the minimum grade percentage needed is given the pass grades. That's where the similarities end, though.
Whereas other systems use the alphabet to indicate the student's accomplishments, a class grade order is used by the UK system. This system dates all the way back to the invention of the university itself and represents the British class system's archetype.
