Alright, here are some you haven’t listed:
Join the Army/Air Force Reserve and take advantage of the education benefits
Take a gap year and apply for the ROTC scholarship (it’s called a scholarship, but it isn’t really the typical one in that you do pay it back serving for at least 5 years)
You could rob a bank or swindle the money (I don’t recommend this)
Purdue has a great program that isn’t technically a student loan. It is a promise to donate the amount they float you in tuition. I’ve only read a little about this.
