This is pretty great, $25 for course work and lectures and you pay $400 for credits only if you pass and like your grade.
Universities should be incentivized for you to pass, not just show up.
Compared to the existing programs where teachers are pressured to pass people because you can't just fail 70% of the students because it makes the passing rate too low for your school?
It would be like today where some public universities with tight budgets that will do pretty much anything to keep international students who pay top dollar.
