Talking about pressure for top grades it is often schools that don't help by measuring, counting and publicising the no of A/A*/9s etc
DD 2 was predicted top grades a couple of years ago and ended up with 8 A and a couple of B's which she was delighted with but got hardly any mention in the schools publicity and was hidden away at the bottom of the website with the focus all on girls with all A/A and no dreaded B's. Luckily I don't think she even noticed. At least I won't have that with DS (not predicted top grades). Needs a 7 or above in maths, a 6 in physics and a 5 in maths to do computing. Oh and 5 passes to get in to the school in the first place.
He found computing easy but I think would have done something very vague and simplistic for the island question and certainly not talked about business models.
And yes the AQA biology is different papers for triple and combined. He should be out now but heard nothing yet.
Repeating best wishes for all those with additional worries this week (been there)
