You didn't mention the age of your children but it can be done, ESPECIALLY if they are old enough to care for themselves after school. I don't know about grants or loans but I do know a lot of people that worked on 12 hour weekends (days or nights) and went to school M-F usually 8-no later than 5. Having one semester of nursing school will let you in on a lot of tech jobs in states that don't require you to be a CNA. I guess since you are posting this in the California board you live there. Do you have have any relatives or friends in other (cheaper states) that can help? Even if it is just an address to get you in-state tuition. Good luck. It will be a very very very hard few years BUT it is well worth it and a great career.
