It all depends on your program and how they calculate the points. Each program is different. I would suggest you contact the academic advisor for the nursing program and meet with him/her to determine what the previous point cut-off was. You'll know you need more than that amount for the next application cycle.
The program I've applied to has a points system that's based on the following: District Residency, GPA, Co-req completion, Paid direct health care experience, volunteer hours, completion of either CNA, Phlebotomy Technician or EMT-Basic. For this program, if you haven't completed all co-reqs, you'd miss out on 46 points (which is a LOT!). A high GPA gives you more points, but you can't get in on GPA alone. While you don't need paid HCE hours, it certainly gives you more points. Same with volunteer work.
So, your best course of action is to meet with the advisor and see where you stand as far as points. They'll let you know if your application would be competitive enough to have a chance to get in. If it isn't, they can help point you in the right direction to make it competitive for the next application cycle.
