Its the Grade that counts. Uni's want to know the grade, not the bands.
It matters what the bands are when you're appealing, because you can only go up one band. If you got a band 6, if you appealed you'd go up to a band 5 if you got it which would still be a C.
for 80% in maths unless you had quite a hard paper its difficult to say if u will get an upgrade
sorry to the english person who got one mark off an a in the prelim. i genuinely think that you may not be successful with your appeal. the higher english and chemistry appeals panel are really strict especially for grade a's!!!
10% rule is not alwayd practical and schools in my area dont really follow it closely. if ur school has a lot of funding thery will pretty much submit whatever appeals they want. dont worry, if you did not meet your estimate grade by one grade you should be able to appeal.
YOU CANNOT APPEAL FOR BANDS! IT IS ONLY A GRADE E.G. NO 6 TO 5 OR EVEN 5 TO 4 AS ITS EITHER AN A, B, C, D OR NA AFTER APPEAL.
