How flexible do you think LSE might be if I fail to make the offer?

I got a conditional offer for International Relations, but I am applying from abroad, with an offer that is not very comparable to UK A-Levels. The offer that LSE made me is I think is much harder than AAA. But I don't think LSE will appreciate that much.

How flexible gneerally are LSE in accepting applicants that nomrally miss grades. Anyone know how high their conditional offers to places ratio is?
Thanks.

To tell you the truth, I dont think the offer you have would be harder then AAA. The course requirement is only ABB. Anyway, I think an institution that takes as many international students as LSE would be able to sort out what the equivalent grades would be in the set of exams ur taking.
Doing int. rel. as well btw- the course looks fantastic.

Conditional offers to places ratio is 3:1 Tom

I was offered BBB

what if I get like ABC or AAD ???

Well I heard elsewhere (can't remember where) that only 10% of applicants fail to make their grades, which I guess is a reflection of the high numbers winning A-Level As or top grades in IB (n the French Bac, only maybe 1% get the top grade - there is not even any data - and the the difficulty of the type of Bac programme is considered even more important than the grade).
The high of offers to places would mean then that there are massive numbers who have LSE as insurance and go elsewhere. And I read elsewhere that LSE is suffering badly now because of the sharp rise in costs (e..g far fewer 31-week rentals!)
The sharp drop in first years enrolled in Iht Relations (from 65 in 2002 to around 45 in 2003) would also suggest either strong desistement, or else no leniency in offers.
I wonder which. Either way, the big variability in places from year to year is quite strange.
