Should I put every college i have ever attended on my application/resume or just those that I graduated from?

I am applying to work at a university that I went to 25 years ago, but i did not graduate from. i also went to 3 other schools before finally graduating from a 4th with bba and mba. should i put all 6 of the schools on my appliation and resume or just the 2 that I graduated from?
