I would recommend looking at all the schools in your area THAT YOU CAN AFFORD and making a list focused on admission requirements.
Some schools (like mine) look only at your science GPA. You can re-take sciences as a refresher and to boost the GPA.
Are you in California? It is tough to get into programs there, not so tough other places. You know what realtors say- location, location, location!
Look at LPN programs- because once you have that credential, getting into a bridge program can be far easier than competing against a bunch of 18yo for a spot in other more competitive programs. (I started as an LPN)
Beware of for-profits. They tend to have lower admission standards, but they also have lower NCLEX pass rates and higher attrition rates.
And if it takes you a year or two to do the above- so what? Honestly, so what? I am the Director of a BSN program and just graduated a 62 year old. He is in good health and was hired right away at his first choice employer. NO ONE in nursing admission cares about your age. It is only YOU who has age as some imaginary barrier.
I hope this is helpful.
