IMO it's fairly random how it all works out except for places that advertise high cut offs like Sheffield. I would apply to the ones you like best and just see what happens. Potentially you may have opened some extra doors by doing the BMAT - you may have got a very high mark for example, and guaranteed yourself an interview - but it's too late now as far as I'm aware the BMAT date for this year would have been earlier so stick to what you've got. Honestly I don't think you can go wrong. Pick it based on where you want to be.
