Psychology at Napier university

I am looking into going to Napier for psychology in 2025 I’m doing 4 higher this year and I do get a B in Nat 5 English last year, but you need to have a C in National 5 maths, I’ve never been great at maths and it is not my strong point I am wondering if this will make me not eligible to apply at all? I’ve seen that some unis will send people on courses to get the qualification over summer. I can go to college for a year and get the qualification, but if I do that it means I need to pay for my last year of uni?
Does anyone have any advice or has went through anything similar?
