When I had crushing student debt, I did the following. I worked part time to supplement my earnings while going to school.
I also obtained Grants and Loans to assist my expenses.
After graduating, I spent a few years paying off my loans.
I also went to school locally so that I could live at home (mostly free) and not have to pay out of state tuition rates at the school.
I also bought used books instead of the new ones. And ate a lot of Mac & Cheese or spaghetti.
And Finally, public protesting at the college about the high rates being asked for tuition.
