"Last year more than 400,000 exam papers were challenged, with more than 77,000 grades being changed." That's 19% of those questioned. My school used to request remarks only for those students who were 2-3 marks away from the next grade boundary up depending on if we could afford it, maths used to put loads of remarks in as they were given the most money to pay for better results as their results affected the school more than my subject (science). If the marks went down then those students were far enough into the grade for it not to drop them a grade they went from high to middle or maybe low, but still in the grade. Presumably those at the bottom end of the boundary would have around a 19% chance of going down, but of course no-one is going to question scraping into the next grade up. A friend of mine questioned one of her daughters gcse exams a couple of years ago, on the re-mark, the overall grade went from an E to A*, they neglected to add all the marks to the spreadsheet apparently.
