Studying nursing in South Africa advice.

Hi, I'm 20 years old living in South Africa and i want to persue nursing. I was hoping someone could give me advice and insight on a few questions. I don't qualify for a degree or maybe even a deploma. I did have Maths lit, Life Sciences and English and passed all but my APS is still at 24. I was thinking of enrolling in a Higher Certificate first since it's NQF level 5 to my understanding. I really have been breaking my head to find an acceptable institution aswell. There are alot of things for me to consider. Private nursing institutions seem too expensive and I'm not even talking about Varsity. I would have to pay for everything myself and simply won't be able to afford it. I really am passionate about pursuing this so if there is anyone who could help i would really appreciate it.
