This response on your previous thread has lots of good advice.
For your situation, I would definitely recommend, as people on that thread did, that you attend community college and see how that goes. Community colleges will have you do placement testing, and if needed will put you in remedial classes to make up gaps in your learning. Community colleges often have resources for helping you explore a variety of majors/careers, and they have typically strong resources for helping you transfer into four-year schools. Many have articulation agreements with state public universities that will either guarantee admission if you meet certain requirements at the community college, or guarantee that credits to take at the community college will transfer.
Community colleges have relatively more flexible scheduling. You could work full-time and take evening classes, or you could take a day classes, or you could take a combination of in person at all. Community colleges are wonderful for people in situations like yours.
