From what you have written, I would go for the second choice. Less pressure, he will still do well and you have the option of the scholarships so there is still a lot to aim for
Yes hubby all makes sense, but DS really wants first choice, and I don't feel it is right to deny him the opportunity now he has made it this far. I guess I am kind of hoping that if he doesn't manage the grades for first choice maybe second choice won't be oversubscribed, and if he just misses out on first choice, maybe they might take him after all (maybe some those they have also offered won't make the grades). If he doesn't make the grade for first choice we do get our deposit back. Second choice is asking for 7s in the subjects he wants to do for A levels, and a total of 36 points. Given that he has an A and A* from last year (old system), he has 15 points already, so if he got the three sevens, he could theoretically get zero for his other six subjects and still meet their cut off (not completely I think they want 5 for English even if he doesn't do it for A level, maths is a given for A level, but you get the point). There is a huge gap between that and getting six 8s (or five more) to get into first choice.
But he wants first choice, he wants the prestige, he wants the opportunities, he is excited about them. What can I say. It just is going to make this year even more stressful than it is already (although maybe not, he has been aiming for this for ages, so some of this stress has already been built in, I think, would have been very depressing if he had not got an offer - even though I was trying to steal myself for it. Good friend (different school, but same primary school) who was the gifted and talented one at primary school where DS was not, didn't get in! Real shame, it would have been nice for them to be together again.
