This is brilliant news! Everyone in my RS class were downgraded regardless of where we were placed in rankings. There were only 10 of us in the class and everyone was downgraded by one grade. I was consistently achieving Bs in mocks and was working to get an A in the real exams. I wasn’t originally going to appeal as I got into my firm uni but when the highest achieving in our class (she was consistently getting As) told me she was downgraded to a B and everyone i spoke to from my class saying they were unhappy with their RS grade, i decided to request to appeal. I think 7 of the 10 of us are appealing as a couple of people aren’t too fussed but a lot of us worked our arses off to get the grades we did in mocks and our school has amazing historical data in RS so there was no reason for Edexcel to downgrade all 10 of us.
