although econ courses are top at LSE a 2:2 is still a 2:2!
A 3rd from oxbridge is still a 3rd, regardless
but your saving grace is that at least its at the LSE!
dont know about jobs, dont major IB jobs require a 2:1 u may be ok!
at the end of the day grades are grades to a certain extent.
my friend got into LSE post grad with a 2:1 from hertfordshire, a tier 3 uni, didnt matter-the selctors were obviously like its a 2:1 regardless.
I also know a guy at accenture doing really well who got a 2:1 from Thames Valley!
so it depends on circumstances, it may not be all about the institution!
But blair did ok for himself with a 2:2 granted from oxford but whats the diff between that and a 2:2 from LSE? nothing really
best of luck
