Sb. said that the MFM program in WBS is one of the top MFE programs in UK, even better than that of IC but it is still not as good as ur previous offers.
So you believe ETH, LSE, U Mich > Warwick Master of financial maths?
How about U of Toronto MMF? (I haven't applied it....but I may apply it if I give up the offers this year...)
On the other hand, IC's Master of Maths and Finance was very good in the past....but some of the best faculties have left...and now only Professor Mark Davis is most reputable...
