DS now has five offers from universities: three Russell Group, one a well-regarded uni but not RG and one a newer university (former poly years ago) offering him BBC (he is predicted AAB). The courses are pretty similar at all five unis (can't go into more detail because he would be furious if he found out I was posting on MN!).
He is adamant that he wants to go to the former poly because he likes it the most. He also reasons that he will have a more enjoyable and less pressurised time there and that he is more likely to get a good class of degree (2.1 or 1st) from the ex-poly - rather than a 2.2 from a Russell Group uni that he just scrapes into. So he is going to firm the ex-poly (he won't have/need an insurance as it is his lowest offer).
AIBU to want him to firm one of the more prestigious Russell Group unis and insure the former poly? DH says I am as it is DS' decision and he's the one who will be going to uni.
