The most common reasons people drop out of college, in my experience:
They weren't prepared for the workload
They discovered they didn't want to pursue that career path
They thought college would be all partying
They weren't prepared for college-level classes, by their high school education
My reasons were I had no money and no transportation. There were limited jobs within walking distance of the school back then. Riding my bike into town wasn't exactly safe. No street lights and their was a rapist running around. I later went to community college instead.
