GI Bill, Hard Work U, correspondence, community college, etc.
I worked my way through college driving cabs and as a part time bouncer. Did just fine ... of course that was back in the 60’s, don’t know if I could do it today.
....also ROTC scholarships, simultaneous enrollment in the National Guard, and, one that I did not know about until too late and regard as the coolest one of all, the “degree completion program”.
Ditto.
