I'd like to apply to unis which are in the top 20 for league tables and stuff (Russell Group and stuff) but most unis seem to want A*AA, AAA, etc for a Maths degree and the only unis which have lower grade boundaries like ABB are the 'less good' unis which I don't really want to go to. Ideally, I'd like to have an insurance of AAB but few 'good' universities go that low for a course like Maths...so I'm not sure if I should risk it and apply to good unis with the lowest of my choices being AAA or apply to an AAB/ABB university too? (which would be a bit safer but I'd be going to a pretty bad uni if it asks for ABB...) Would it be a waste?
