i need some serious help and advice

I took a quick CNA course at a local private school. When i seen it advertised on tv it said that it only last 3-4 weeks during the day. well that caught my eye even though my mother warn to me that it was a bad idea because they say one thing and mean the other so she didn't help me pay for the program. the program cost 750. i figured it would be easy because i took the class at a local technical college but i failed it (teacher was a butthole). i did very well at the local private school passed and everything. Well i been done with the class for over 4 months. I can't take my certification test until i pay the whole 750. i'm only down to 450.

I also take night classes (A&P) at a community colllege for RN. I can't work at my job during the day because it is filled. My plan was to work as a CNA during the morning and go to school at night. but with the program not paid for i'm SOL. WHAT should i do?
