I studied HS and college here in the UK and the grading system is different. So I shall share the list of grading system here. HS: (GCSE) The pass grades, from highest to lowest, are: A* (pronounced 'A-star'), A, B, C, D, E, F and G. Grade U (ungraded/unclassified) is issued when students have not achieved the minimum standard to achieve a pass grade; the subject is then not included on their final certificate. Sixth form (college): A � top 10% B � next 15% C � next 10% D � next 15% E � next 20% O (Ordinary) Level � next 20% Fail � final 10% My highest grades in: HS: A*'s in French, Drama, Chemistry and A's in English Language & Literature, Biology, Food Tech and Religious Studies. College (6th form): A in French and B in Chemistry & Psychology.
