I got screwed in 2008 when my mom was denied the PLUS loan. I tried talking to student financial services for advice. After talking to the dean of my college, I received a large grant in order to cover my senior year. I thought I wasn't screwed anymore, but I got screwed again because nobody told me that a whole other part of my financial aid, "need-based" aid would disappear because my parents are expected to pay so much, regardless of their ability to do so. After that I was still able to pick up a few more grants and scholarships. However, I ended up having to take out private loans to cover much of the rest. I very much do not recommend taking out a private loan to pay for college.
I'd say I'm well-informed now but I learned nothing about my loans until I graduated.
