Will I be accepted by Birmingham if I missed out by one point in ib math ?

I'm currently an ib student hoping to study business management at university of Birmingham this September but I'm worried I won't meet the requirement grades for math. My requirement for Birmingham is 32points and 17 points for high level subjects and grade 5 for math. due to the leaks that is happening in ib final exams, the grade boundaries might be higher for math and the requirement for math is 5 but I am not sure if I will get 5 or not, I’m worried that I will get a 4 . as I really struggled in gaining high marks in math and if the grade boundary gets higher than there is a high chance I might miss my requirement grade for math.
Would Birmingham accept me if I miss out by one grade only in math? I think I can met all other requirements which is 32 points and 17 in high level subjects, the only requirement that I might not meet is grade 5 for math which I perhaps will get a 4.
