I dropped out after 10th grade and went on to Iowa State. They had an 'exceptional student' admission clause, and I suspect most universities do. I'd taken summer classes there for a few years and had a professor write a recommendation, that combined with SAT scores seemed to be more than enough. It worked out great for me, whereas high school was not going so well for me socially. I lived at home the first semester and then moved in with some friends. I'd recommend it for a mature 15 year old. But looking back, even for me, the situation could have gone either way depending on who I met at that point.
