Bangles,I'd say you've done the hard task already, getting into a big 4 consultancy with anything other than 1st/2:1 is extremely difficult (although not impossible!)as far as future opportunities goes to get into an MBBB you'll most likely need an MBA and a top business school.Their notoriously difficult anyway but i wouldn't let your first degree get into your head too much, your in a top firm. well done :)
