What are the chances of getting into a nursing college?

Hey guys I’m currently studying a diploma in real estate but find that I’m quite unhappy with what I’m studying.

I’m 3 years into it (this is my last year). I wanted to switch to nursing at my uni (CPUT) and was going to but very unbelievable circumstances blocked my switch. I’ve since decided to apply to nursing colleges for a higher certificate in auxiliary nursing. I want to find a way to get into nursing and I’m just asking what are the chances I get into one of the following colleges I’ve applied to?

Mediclinic Western Cape college of nursing Life Healthcare

I passed my matric with a bachelor but I have maths lit and my life science (my lowest mark) is a 3 (40%). My other subjects are all 4s and 5s.

Any advice would be greatly appreciated as this is something I’ve thought long and hard about and have been honestly itching to study for the past 2 years of being in uni
