1.Why don't you request them to convert as 12 month program?
2.As far FT rankings are concerned Birmingham is marching upwards but the bitter truth is career support is not up to the level..... Out of 640 business graduates 250 are from FT MBA program....Supporting 250 FT graduates ( that includes 12 month,21 month,MBA in banking,MBA in Fin,supply) etc for placement is a big task.
3.Location advantage of Birmingham helps to recover from all difficulties.
4.This year both univ are going to be audited...I don't know what will happen.As you know some of the good univ like Leeds,Nottingham had lost their places.
5.Though Brad is in downward trend its going to be triple accre...by this year....It may help to survive in rankings....
6.Anything which is above 50 in FT is not a good choice.So from this point of view both are average.
7.Despite many difficulties Bradford has shown good consistency....by at least occupying some position.
So from your point of view I think Bradford could be a right choice..Spending 21 month for a program will be hectic....
