University of Liverpool Urban Planning UCAS choice

Hi, my top choice is Master of Planning (MPlan) at the University of Liverpool, in which the entry grades are ABB.

I have also applied for Urban planning at Liverpool which requires BBB grades, and Urban and Environmental planning at LSBU which requires BBC.

I am ready to accept my offers from UCAS, and I am ready to put down the Mplan at Liverpool as my first choice and LSBU as my insurance choice.

If I happen to fall short of the ABB grades necessary for the MPlan, what are the chances I can still take the Urban planning course if I for example get BBB? Should I still put LSBU for a saftey net or put both Liverpool courses down?

Thanks.
