Having taught seniors for 19 years, I can tell you that I've never had a senior earn a scholarship for something "odd".
I worked in the Financial Aid dept for undergrad and graduate school. There were a TON of "bizarre" criteria scholarships.
I went to a very large Texas University. My dad was of the VP's of the university.
I had a parent living, working and paying taxes in Texas from the time I was 3 years old but since my parents were divorced, I graduated from a HS in another state. I had to pay out-of-state tuition. It was because my mom claimed me on her taxes and not my dad.
I thought that was completely riduclous!
