Some facts: - Grade boundaries are not determined before the exam - Grade boundaries are not set to "make it harder" for you - Grade boundaries can go up or down in any given year - Grade boundaries are set after exams are completed and marked - Nobody, I mean absolutely nobody, including the exam boards and the people who set the boundaries knows that they are going to be in advance. This is determined after all papers have been marked. Anyone who says "I think this" may as well also go and buy a lottery ticket because they have the same knowledge about those numbers as they do the grade boundaries i.e. they know nothing.
