Appeals will be a mess with teachers taking flack.
Appeal 1: final grade and actual grade don’t match, admin error school/SQA agree and sort.
Appeal 2: little Jimmy didn’t get the grade he needed in assessment. Find evidence to support upgrade, which won’t exist because we’d have used it. Teacher error in not giving enough assessment opportunities of the correct standard.
As for changing questions, it has long been held that you can change part of prior-verified questions as long as the question stays fundamentally the same. Eg in chem changing a Mg ion to a Ca ion or numbers in a calculation, which is what I’m doing for a AH paper.
