FF - // But you will probably find, andy, that that school still has ended up with more A* students than it normally had, and probably more A/Bs, in lieu of Cs.
Having said that, how on earth you downgrade a single person's prediction that much without going back to check first with the school or to check the data input is a mystery. An alarm bells should have rung and a discussion/negotiation should have taken place. //
What is fundamentally unfair about the current grading system the government has used, is that it is based on the exam profile of the school.
That means that a school with an intake of exceptionally gifted students, and correctly predicted high grades for them, will see those students downgraded purely on the basis of the past exam history of the school, over which they have no control, and to which they have had no input.
That cannot ever be seen as a fair and just system to award grades that are going to affect students' future career paths, and future lives.
