from $500 to $1000. In most cases, if you have a decent GPA, you can get a half tuition scholarship there and if you have a really good GPA, full tuition.
I think it's pretty amazing that the Church is able to provide a 4 year degree in mass like that to the general membership. I can't think of many other situations where a private organization provides a quality 4 yr degree for that cheap. BYUI isn't going be in any top 50 academic rankings, nor is that their goal. My company recruits there and we've hired some great graduates. They also have a growing group of international students from Africa and elsewhere whose lives are being greatly blessed through the opportunities of a 4 yr degree.
This is the kind of thing I'm glad the Church is able to do with all their resources.
