Hi buddy, firstly welcome to gmatclub, here, you do not need to post everywhere to get a response. One post here in the main schools thread is more than enough. I had to learn about deleting merging and splitting before I could rejig your post here
Secondly - many many congratulations on your IE and Oxford admits + all the waitlists. Such success in an application season is pretty uncommon.
To compare the schools we use the following thread :
ranks-and-clusterings-of-various-international-b-schools-78320.htmlAs you can see here, we consider Oxford an Elite school and IE a near-elite due to various factors (such as perceived brand, placements etc.). We have a strong contingent of Oxford folks at gmatclub who have done a wonderful job of advertising their school here :
sajid-business-school-university-of-oxford-78371.htmlI have some experience with the LBS waitlist and I will talk about it further. From my experience, LBS rarely admits waitlisted candidates till the very end (i.e. July/August). However, LBS is one of the rare ultra-elite schools that looks at you seriously if you stick with the waitlist till the very end (i.e. you show that you really really want LBS). If you don't withdraw, by August, you will either be :
a) Admitted (tougher this year than others because of the high volume of applications)
b) Deferred (if they think that you were good enough to admit, but they couldn't because they filled the class already)
c) Special consideration for 2010 (if they think that you were close and with some minor improvements, will make the cut).
I had to deal with option c last year. For special consideration, I sent out an updated CV and a letter and I was admitted by September 2008 for class of 2009.
To choose you should look at your situation closely. The most important thing to consider would be when do you want to graduate ? Realistically, LBS in 2009 will be tough, simply because by the time they decide in 2009, it might be too late to attend Oxford. There is a strong chance that you might get admitted to LBS for class of 2010 (but then there is a slight chance that you wont - if that happens you still have IE in the bag). If you join class of 2010, you study further into the recession and perhaps graduate at a much better job market. On the other hand, if you want to attend a school and graduate ASAP, then Oxford and IE already present fantastic options.
Good luck.
