Thank you for your reply. Correct me if I'm wrong the overall grade is an average of the 4 modules. So if someone achieved two B's at AS at 76 (unit 1) and 65 (unit 2) (2016 boundaries) and the A boundary this year was 82 (unit 1) and 72 (unit 2) the person, in order to achieve A at the end of the two year course, would have to achieve 6+7 marks they did not gain first year and the required marks for an A in unit 3 and unit 4
