Hi Leonardo,My son’s and daughter have moved back and forth between the Italian and Uk system.Don’t despair, my middle son left school at age 16 having taken no Italian exams except the licenza media (at 14yrs), he started school in the Uk and did his AS and A2 exams at 17 and 18 and got into university with NO GCSEs! The 6th form he went into were very understanding and thought that his years in the Italian system were a bonus as he was able to add Italian A level to his other subjects.Deborah
