After getting accepted by a school, my older son and his wife both applied for every kind of scholarship they could. They got a few and lost out on others, but they never stopped applying. Then to fill in the majority of the funding the colleges had student loan programs that were federally funded, and they took those when the savings bonds we had for education ran out. Yes, they have debts, but they've got jobs in their fields of study (daughter in law is and art teacher, and my son manages a computerized order system for a large online retailer).
My son did this while working full time. He didn't show much interest in school, or promise in achieving his education goals until he was 26. But I can't say enough about how good I feel for him. It wasn't easy, but he's happy and proud that he got through it. The bad thing ... since I started transition they don't want to see or talk to me. I had to ask my wife to send him an extra graduation present for me, and to say it was also from her.
