It is possible. Go to a community college for your associates degree then to a state school. Add-in some correspondence courses and you have a degree relatively cheaply. Of course, you’ll also work part time during this. I know it takes some hard work, but so what? Remember, the average college student in order to graduate in 4 years has 15 hours PER WEEK in class. The average student should stop whining and start working hard. It can still be done.
In order to get my engineering degree in 4 years, I would have had to average over 19 hours in class per week. Each of those hours required 2 to 3 hours outside of class for an A~B average.
I tried to keep that schedule for over a year, while doing just a little side job for spending money. It was not possible and keep sanity. I stretched it out to 5.5 years. I worked long hours during the summers and breaks but I could not have made enough to pay tuition and board in less than 10 years.
That was starting 3 decades ago. Now jobs are mores scarce and college way more expensive. It would take a very long time to complete while covering all cost on your own and getting zero debt.
