I'm primary so a bit clueless about exam boards.
DS is in Y11 and doing the above GCSE. He's set for 9s in Biology ad Physics but only a 7 in Chemistry (most of the class seem set for a 5/6 which seems so much lower than all the other subjects?!). Can anyone explain to me how they work out the two grades you get at the end?
Does it have to be 9-9, 8-8 etc? or can it be 9-8 or 9-7? What would you get it you got 9 in two of the and 7 in the other??
Any advice much appreciated!
