Life never seems to treat us poor naive little mathematicians fairly
Ah well, we're just too awesome for people to deal with
But yeah Warwick is supposedly the best uni after oxbridge for maths. And that's the same offer I have, but it just seems like it's not worth all the extra STEP work just for Warwick when I could go to Imperial or Durham instead and not have to go through STEP. Yeah STEP is like A-level maths, but much harder because it's more spotting tricks and using clever methods rather than just repeating formulae you've practised,
I don't know anyone who would do STEP unless they had to...But Durham is very nice, I heard back from castle just over a week ago, it's such a nice college, but really competitive. But for your friend it might as well be an offer, it means your department wants you and just needs to find you a college to live in, though track takes a couple of weeks to update. Best of luck to him castle is so nice, I'd feel really bad if he didn't get a place at castle because of me, even though I'll probably reject it if I get an offer from Cambridge.
Which Cambridge college did you apply to? And I see you're going for medicine, best of luck
