Help with Textbooks for Prereqs

I am a single mother of 2 children. Age 3 & 10. Aside from my children I also take care of my mother who has been removed from the workforce because of medical issues. I am no stranger to hard work, however this matter is on a time frame do my back is against a wall. With no other resources or options, here I am asking, wishing & hoping for any kind of relief!! All help is appreciated. Thank you
