how lenient is ulster university with grades?

Ulster has released their new msat to get into certain courses.
I’ve passed and been offered a conditional of BBB. if you don’t meet the grades, how likely is it that you will get in if you just miss them.
i’ve also heard if the course isn’t oversubscribed then they accept ppl on the course and my course isn’t oversubscribed, as far as i’ve been told.
if anyone can kindly help
