Hey Bsc. Management is my firm choice at Warwick, and so far you are the only person Iv'e heared of whose got on offer to read Managament (here at TSR at least!).
The courses is probably more interesting than accounting and finance because it covers the qualitative aspects of business development as well.
WBS is the second best business school in the UK and one of the top rated business schools in Europe.
Im not paticularily fond of accounting, I prefer analysis and finance but Im sure you can work around what electives you want to take.
