I would've said no however the further maths and A* in maths could make you stand out a bit, as in they'd be more favourable of you but that depends on the course you wish to apply for. If you get a good reference you might get an A*AB offer or they could just give you a shot with AAA and see if it works out, they might and could even bring your AS further maths into the offer so A*ABa. I wouldn't say it's a dead end and you stand a good chance
