Worth applying to bath with my gcse grades

hi, I would like to study accounting and management at bath, they require a 6 for math's but I only have a 5, but they will accept with a grade 4 if people apply for contextual admissions which I think I do as I live in a deprived area, Also I moved to the UK when I was 17 and made to do only 2 GCSE within a year

my current a level grades for yr 12 are A*A*A*

Is it worth applying and what are my chances.
