AQA English here. DS said the "40 marker was about over-protective parents so I knew a lot about that" 😂
Same A level choice here fleur geography, business and biology. For his first choice sixth form he needs an A in biology which he may not get so psychology is his back up. If he doesn't get the required 5 Bs for his first choice then he doesn't get in. Simple as that.
He has welcome days at both first choice and 2nd choice sixth forms. the grades in August could be very variable, at the moment I think 70/30 or 60/40 he'll get in the first choice but definitely not certain at all. Which is why I think it's important he goes to both welcome days.
