I know that many years back UD had placement exams, but I still wonder whether there were entrance exams when Sheen applied.
I know UD had a great great scholarship program through which the top students in each Ohio HS could attend UD. I think they got free tuitition. Maybe Sheen deliberately failed some exam that would have given him a scholarship. With 10 children in his family, I guess a scholarship would have been nice.
At any rate, UD was about the least expensive Catholic college in the nation back in the 60's.
