Yes, I have applied at a lot of schools, among them:
LSE => No offer
Warwick => No offer
HEC Paris => No Offer
IE Madrid => Offer
Cass => Offer
LBS => Pending
StGallen => Pending
In general, I think SSE is an excellent school. It is accredited by EQUIS like a lot of other Top Schools and SSE is especially well known for academic excellence (especially in Finance and Economics) and I am not sure whether that statement is valid to the same extent e.g. for Cass Business School. SSE is a CEMS Partner and its partner universities are top notch (LSE, Wharton, Columbia, NYU Stern etc...) so I think whereas the MSc Finance takes two years, one major advantage will be to visit another top US-university for at least one semester.
And as a EU-student, SSE is free of any tuition fees. However, I have a hard time in deciding between Cass and SSE because Cass has an excellent network and good placement at BB IBs.
On the other hand, some people already told me that I should be very happy to get an offer from SSE with my bad GMAT, especially since competition for the MSc Finance seems to be very hard. One guy I told to was even very surprised that Warwick did not made me an offer whereas SSE did.
